In order from longest wavelength (smallest energy) to shortest wavelength (highest energy):

Two members of staff are using two way radios. Each radio consists of a transmitter and a receiver. At what speed do signals travel between the two way radios?
they travel at the speed of light.
radio waves are one part of the electromagnetic spectrum.
All electromagnetic radiation travels at the speed of light

when people or governments use radios to communicate how can they do it without someone just tuning to the frequency and just listening to everything they are saying? how come 2 people cant be broadcasting on the same frequency? there cant be that many frequencies where everyone can have their own right?
Radio waves are electromagnetic [...]

I found this really neat radio and wasn’t sure if it would fit in different model cars. Do most radios fit?
Yeah… most radios will generally fit any car. Usually, you have to buy an installation kit made to fit your particular car and the size of the radio you want to install. The kit [...]
