Turn on the radio. A program will come out from a broadcasting station miles and miles away. We know that sounds and music themselves couldn’t travel that distance through space .There must be something that brings the program from the station. But what is this silent carrier ( 载体) ?

This is known as radio waves. However, we can’t see them or even hear them. In fact, nobody knows exactly what they are. Nevertheless( 然而) ,we know that they are made by electricity .

At the broadcasting station, people talk, sing, play musical instruments or make many other sounds. These sounds are changed into electricity. Then from the broadcasting aerial (天线)of a tall tower , electricity sends out radio waves which travel in all directions .And some of them reach your radio aerial. What happens next is a magical thing. The radio waves start an electric current ( 电流) in your aerial like the one that was first made in the broadcasting station . Finally, the loudspeaker in your radio set changes the electricity into sound .Therefore, you hear the program.
