So, how does it work ? Let’s take a radio programme as an example. Firstly , in the studio the studio the voices and music are turned into electronic signals, called ‘voice waves’. Next, they are made stronger by passing them through an amplifier. These stronger waves are called ‘carrier waves’ and they are passed to large aerials. Then the aerials send out these waves, which are now called ‘radio waver’. These are subsequently picked up by a receiving aerial, in this case, the one on your radio. After this, the radio waver go through a reverse process. They are first turned back into voice waves, then passed through another amplifier, and finally sent out through speakers or headphones. The result is your favourite music or the latest news!
