If you connect regular headphones to the microphone input, you can use them as a microphone. Simplified, the design of headphones and a microphone is the same: the membrane is connected to a coil with a wire located in the magnetic field of a permanent magnet. In headphones, during normal use, the current applied to the coil is converted into membrane vibrations, and vice versa in a microphone.

If you find yourself in a falling elevator, the best strategy to increase your chances of survival is to lie on your back and try to take up as much floor space as possible. In this case, the impact force will be maximally distributed over the surface of the body. It is widely believed that you just need to jump during the impact, but this misconception is unlikely that someone is able to accurately guess the time of the impact and jump at the same speed as the elevator falls.

To see through glass with a matte surface, just stick a piece of transparent tape on it. Due to the irregularities of the frosted glass, the light is scattered, but the adhesive side of the adhesive tape smooths out these irregularities, and as a result, the light passes as if through ordinary glass. I must add that if the surface is matte on both sides, this trick will no longer work.

There is an optical phenomenon that can be called an inverted rainbow, although it happens very rarely. Such a rainbow appears only when several conditions are met. In the sky at an altitude of 78 km there should be a thin curtain of cirrus clouds, consisting of ice crystals, and sunlight should fall on them at a certain angle in order to decompose into a spectrum and be reflected into the atmosphere. The colors in the upside down rainbow are also reversed, with purple at the top and red at the bottom.

A bird sitting on a wire of a high-voltage power line does not suffer from current, because its body is a poor conductor of current. In places where the bird's paws touch the wire, parallel connection, and since the wire conducts electricity much better, a very small current runs through the bird itself, which cannot harm. However, if the bird on the wire touches another grounded object, for example, the metal part of the support, it immediately dies, because then the air resistance is already too high compared to the resistance of the body, and all the current goes through the bird.

If a boiled egg is spun on a smooth surface, it will quickly wrap in a given direction and will rotate for quite a long time, while a raw one will stop much earlier. This is because a hard-boiled egg rotates as a whole, while a raw egg has a liquid content that is loosely bound to the shell.

Knowing the designation of the elements of the electrical circuit is an important condition for the formation of physical literacy of students. The school physics course offers a whole list of vocabulary words, symbols, formulas, notations for memorizing and writing them.
The interactive simulator is designed to introduce the designation of electrical circuit elements. The work was done on the basis of a template for creating interactive simulators with the "Screen" technological method in the Microsoft Office Power Point program, as well as using a template made by N.N. Pokrovkova.

These presentations are a small stage of the lesson where the teacher will show the sign, appearance and a picture of the element being studied. I have two presentations for two different lessons.

The first radio was not at all like modern radios.

The message was transmitted using Morse code

The first message consisted of only 2 words "Heinrich Hertz"

Heinrich Hertz is a German physicist who experimentally proved the existence of electromagnetic waves. The unit of frequency, 1 Hz, is named after him.

“I am proud that I was born Russian. And if not contemporaries, then perhaps our descendants will understand how great my devotion to our Motherland is and how happy I am that a new means of communication has been opened not abroad, but in Russia. Popov A.S.

SOON THE INVENTION OF A. S. POPOV STARTED TO BE USED IN THE RUSSIAN FLEET

Popov was followed by the Italian inventor Guglielmo Marconi. He improved Popov's radio and received a patent for it.

Marconi increased the communication range to thousands of kilometers and organized the industrial production of radio receivers. It was with the help of his radio that the SOS signal was sent from the Titanic.

In 1909, Marconi received the Nobel Prize for his work in the field of radio communications. A. S. Popov had already died by that time.

Years passed, the appearance of the radio changed ...

There were TVs, radars ...

The time has come for radio telescopes, cell phones ...

Modern Information Technology would have been impossible without the invention of A. S. Popov

Radio Day is our common holiday. Congratulations!!!

Actions of electric current Grade 8

Electric current is the directed movement of charged particles. In metals, such particles are electrons.

It is impossible to see the movement of electrons along the wires, therefore, the presence of current in the conductor can only be judged by its actions on surrounding objects.

Actions of electric current: thermal and light, chemical, magnetic, mechanical.

Thermal effect of current The thermal effect of current is based on the fact that any conductor through which current flows heats up and gives off its heat. environment. This principle underlies the operation of any electric heater.

The use of the thermal effect of current in everyday life

Light effect of current The light effect of current is connected with heat. If a metal body is heated to a certain temperature, it will begin to glow. This principle underlies the operation of an electric incandescent lamp.

The chemical effect of current The chemical effect is due to the fact that the current, passing through solutions and melts of substances, can cause a reaction. As a result of the reaction, pure metal will be released on one of the electrodes.

Applying the chemical effect of current Since the mid-19th century, the chemical effect of current has been used to deposit thin layers of silver on a cheaper substrate.

Magnetic effect of current The magnetic effect of current is due to the fact that a magnetic field is created around any conductor with current, which can affect some bodies.

Application of the magnetic action of the current Electromagnets are the main component of electromagnetic cranes, magnetic locks, electric bells, loudspeakers and telephones.

The mechanical effect of current The mechanical effect of current is due to the fact that a current-carrying coil placed in a magnetic field is subjected to a force that causes the coil to turn. This principle underlies the operation of all electric motors.

Application of the mechanical action of current Electric motors are widely used in everyday life, industry, and transport.

The magnetic effect of the current underlies the operation of electrical measuring instruments (ammeters and voltmeters).

Thanks for attention. We wish you success in your further study of physics!

Law of refraction of light

Refraction is a change in the direction of movement of a light beam at the interface between two substances.

The incident ray, the refracted ray and the perpendicular to the point of incidence lie in the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the relative refractive index of the two media.

Refraction of light at spherical surface glass is used in lenses.

Energy-saving lamp Ogorodova Valery 8 class "B"

An energy-saving lamp is an electric lamp that has a significantly higher ratio between luminous flux and power consumption compared to incandescent lamps. As a result, their use contributes to energy savings.

Types of energy-saving lamps Fluorescent lamps LED lamp

Fluorescent lamp A fluorescent lamp is a gas-discharge light source. Consists of a tube coated thin layer crystalline powder - phosphor. The tube is filled with an inert gas or a mixture thereof. A dosed amount of mercury is introduced inside, which, when the lamp is operating, passes into a vapor state. The tube is hermetically sealed. At the ends of the lamp there are sockets with contact pins for connecting the lamp to the circuit.

Types of fluorescent lamps Compact fluorescent lamp Linear fluorescent lamp

LED lamps LED lamps use light-emitting diodes as a light source. An LED is a semiconductor device that produces light when an electric current is passed through it.

Key Benefits Energy Saving Low Heating Long Life Energy Saving Lamp Warranty

Who invented the lamp? The main inventors of the incandescent lamp are T. Edison and A.N. Lodygin. But in fact, this invention is the result of the long work of many people, such as P.N. Yablochkov, V.D. Coolidge, D.W. Swan, and many others.

Emission of light People have noticed for a very long time that metals, when strongly heated, begin to emit light, the color of which depends on the heating temperature. This is the principle upon which the operation of the incandescent lamp is based, as was said earlier. RED ORANGE YELLOW BLUE WHITE

Early successes The main problem in trying to invent an incandescent lamp was the melting of many metals with strong heat. To do this, the light bulb filament had to be created from metals whose melting point is very high. Therefore, the thread of the first lamp (Delarue, 1809) was made of platinum (melting T = 1750), but even this was not enough for normal illumination of the premises. In 1838, Jobar invented the first lamp, which used a carbon rod as a filament.

Edison In the second half of the 1870s, the American inventor T. Edison research work, in which he tries various metals as a thread. In 1879 he patents a platinum filament lamp. In 1880 he returned to carbon fiber and created a lamp with a lifespan of 40 hours. At the same time, Edison invented the household rotary switch. Despite such a short lifespan, his lamps are replacing the gas lighting used until then.

Lodygin A.N. Lodygin in the 1890s invents several types of lamps with filaments made of refractory metals. Lodygin suggested using tungsten filaments in lamps (these are used in all modern lamps) and molybdenum and twisting the filament in the form of a spiral. He made the first attempts to pump air out of the lamps, which kept the filament from oxidizing and increased their service life many times over. The first American commercial lamp with a tungsten filament was subsequently produced under Lodygin's patent. He also made gas-filled lamps (with carbon filament and nitrogen filling).

Modern lamps In modern incandescent lamps, the filament is made primarily from tungsten. The flasks of these lamps are filled with heavy gases, which greatly increases the light output (the first lamps had vacuum). Incandescent lamps have changed a lot in their history and have experienced a lot, it is possible that soon humanity will invent a new type of lamp that will replace modern ones.
