Wavelength is the distance between two corresponding parts of a wave, while frequency is the number of waves that pass a point in a certain time. Wavelength times Frequency equals Speed.

Every wave has a different wavelength and Frequency.

Radio Waves have wavelengths from 1 milliliter to 100 kilometers and a frequency anywhere from 3GHz to 300GHz. They're used for radio programs and TV.

Infrared Rays can be used to heat food or for a remote. They have wavelengths from 300 GHz to 430 GHz and frequencies from 430 THz to 300 GHz 3.

Ultraviolet Rays have wavelengths of 10nm to 380nm and a frequency from 8x10^14 to 3x10^16. Hospitals use Ultraviolet to sterilize equipment and to treat vitamin D deficiency.

Gamma Rays have a Frequency greater than 10^19 Hz and wavelengths less then 10 picometers. Gamma Rays are used for killing cancer cells, Sterilizing equipment and in radioactive tracers.

X rays have frequencies from 30 petahertz to 30 exahertz and Wave lengths from .01 nano meters to 10 Nano meters. They're used in hospitals for taking pictures of bones.

Microwaves, with a frequency anywhere from 300 MHz to 300 GHz and wavelengths of 30 cm to 1 mm, are used for heating up food.

The only waves on the electromagnetic spectrum we are able to see is Visible light. Visible light has wavelengths from 390 to 700nm and frequencies range from 430 to 770 THz.
