Answer 1

The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves. Radio waves are used to transmit information from the antenna of a broadcasting station to the antenna of your radio or TV. In astronomy radio waves are used to gain information from distant stars using radio telescopes. Radio telescopes have the advantage that radio waves are not blocked by conditions of the Earth's atmosphere as light waves are.
