In the room where you live there are hundreds of strange, invisible magic waves. They come into your house through the walls, ceilings and floors and they are there now. They are upstairs and downstairs. They are all over the world, surrounding everything and everyone. Yet no one can ever see or hear them or feel them. But we know they are present. All we have to do to prove it is to turn on our radio and television sets. Then we pick them right out of the air and transform them into music and voice that we can hear, and moving pictures that we can see.

These magic waves come from everywhere. Turn the knob of your radio just a little, and you may hear the latest news. Turn a little more and you can hear a concert. Turn the knob of your television set and with the help of these same waves you will see a film or a play.

All you need to do is to take the set into your room and to turn some little knobs.

When you turn the knobs of your television set, you release sound and light waves and you can both see and hear programmes. When you turn the knob of your radio, you release sound waves and you hear a programme.

How are these waves brought to your radio or television? There is energy working around us all the time. There is the energy in light, heat and sound and it travels in wave. A wave is a single vibration of energy in motion.

Light and heat and radio waves are different from sound waves because they do not need anything that we can see or feel through which to travel. Light and heat and radio waves are called electromagnetic waves. And because they are electric they are surrounded by the magnetic fields that electricity always makes around itself.All electric current creates a magnetic force, an area around that has the same kind of power that a real magnet has. This magnetic area is called a magnetic field.

First of all we want to tell you that the sound wave is called audio frequency wave (from ―audio‖ meaning ―to hear‖). We must remember that the radio waves that come from radio stations are very rapid in their vibrations. They alternate between positive and negative charges from 1 000 000 to 10 000 000 times per second and that is too fast for the loud speaker of our radio sets. Our radio loudspeaker could never receive waves that vibrate as fast as that. The radio waves that come into our sets are produced in the radio stations by alternating current like the spark between your finger and the metal door knob. An alternating current is a current that changes from positive to negative hundreds of thousands of times per second. First it has a positive charge, and then it has a negative charge, and it keeps on alternating from positive to negative so rapidly that you cannot notice the changes. You have just the same thing in the cinema: you see the film but you cannot separate one picture from another, while watching the film. This alternative current is sent up a tall metallic shaft and out in space. Before this current is sent out, it is made very strong with the help of vacuum tubes. As soon as the alternative current enters the shaft it is turned into radio waves. The alternating current that is sent up the tall shaft out into space usually carries the sound wave which, at this point, is in the form of much slower electrical vibration that we send through the telephone wires. Because of carrying these waves it is called a carrier wave. Sometimes it carries nothing at all, but most of the time a sound wave is riding on it. By the time hundreds of different carrier waves reach you radio, they are quite weak and cannot be used.They cannot be sent into the electromagnet of the loudspeaker because they will produce no effect, i.e. they will create no sound in your loudspeaker. These radio waves can produce sound in the loudspeaker only after we have solved three problems. First, we must separate them and take only wave frequency second; we have to strengthen greatly these weak waves. And third we must separate the sound wave from the carrier wave. Only after that we can get the same sounds in our loudspeaker as those sent into the microphone at the studio.

2.Відповісти на питання

1. How is the sound wave also called?

2. How often do the sound waves alternate?

3. What is an alternative current?

4. Why is a carrier wave called so?

5. What is usually riding on it? 6. Why can’t we use different carrier waves by the time they reach our radio? 7. Name the three problems we must solve to produce sound in loudspeakers.
