Question

2-way radios take sound waves and convert them into electrical signals. Then, they are converted into

radio waves to transmit them to the receiving radio where it is converted back into sound waves.
Your principal is using a walkie-talkie (2-way radio) to communicate with your bus driver. What are the
wave conversions that occurred from the first radio transmitting the person's voice to a second radio?

Answer 1

Radio waves are transmitted from a sender to a receiver.

However, these waves may be modulated.

There are two kinds of modulation:

AM - amplitude of the electromagnetic waves is slowly changed

FM - frequency of the electromagnetic waves is slowly modulated

A person's voice is used to modulate the waves as they are sent from the sender to the receiver.

The modulation is converted by the receiver from electromagnetic waves to audio waves.

These audio waves are used to produce an audio signal that can be interpreted by the person using the receiver.
