The Electromagnetic Spectrum

 

 

The sun is a major source of energy for changes on the Earth’s surface

 

 

 

 


The sun loses energy by radiating light, gas and particles

 

 

 

A tiny amount of that light reaches the Earth, transferring energy from the sun to the Earth.

 


The sun’s energy arrives as light in the form of waves.  There are many different lengths of waves.

 

 

Each type of light has a different length of wave. 

 

 

 


Infrared light is a longer wave than visible light.

 

 

 

Ultraviolet, X-rays and gamma rays are shorter than visible light.

 

 

The shorter the wave length, the more energy the wave has.
