Radio wave is a form of an electromagnetic radiation that include wave lengths in the electromagnetic spectrum.

What a radio wave is what's known as a carrier wave.

A radio transmitter sends out waves at a certain frequency .

These are then picked up by the ariel of the receiver as tiny eclectic currents when the wave passes through it.

Two examples are AM and FM.

Shows the different frequency for different waves of the spectrum.

A mobile phone works on the same principle as radio waves.

On the spectrum its frequency is roughly about 10.8 ghz

A mobile phone contains a small transmitter which works on about 0.75 to 1 watt of power .

This sends an encoded radio signal to mobile phone which picked up by the phones tower and decoded.

X ray is a form electromagnetic radiation The wave length of 10 to 000.1 nanometres This high energy corresponds with shorter

waves .To create an x-ray, a cathode is heated to a high temperature. This effects electrons to break away from the cathode. The anode through the vacuum tube has a high impending difference, so it attracts the electrons at great speed. The electron's collision with the anode causes an x-ray photon to be released.

Infrared is a form of energy that is part of the electromagnetic spectrum.

Infrared goes in-between microwaves and visible light. Because its waves are shorter than microwaves but longer than visible light.

Infrared stands for anything that lets of heat.

Equipment such as night vision goggles or thermal imaging use infrared.
