Although they seem different, radio waves, microwaves, x-rays, and even visible light are all waves of energy called electromagnetic waves. They are part of the electromagnetic spectrum, and each has a different range of wavelengths, which cause they waves to affect matter differently.

Radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM ... X-rays: Your doctor uses them to look at your bones and your dentist to look at your teeth.

As the wavelength of waves in the electromagnetic spectrum gets shorter, the energy being carried by the wave increases. The examples mentioned ... The diagram shows a floodlit building which uses 'sodium vapour' lights which produce a nearly pure orange light with a wavelength of 600nm (see section 'Powers of 10').
