frequencies. Broadcast involves using radio waves also known as
electromagnetic radiation to send signals.

i should imagine its because EM waves can travel through a
vacuum so that's why it is possible for satellites to broadcast
information from impulse signals sent from outer space

The radio receptor receives electromagnetic waves from a broadcast station.
These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.

There are five characteristics of radiation. They are time
delay, penetration power, ionization, fluorescence emission and
film exposure. Radiation can also be used in treatment by internal
contamination or external exposure in case of emergency.
