X-rays- describe radiation which is part of the
spectrum which includes visible light, gamma rays and cosmic radiation.
Unlike visible light, radiation passes through stuff.
When you shine a beam of X-Ray at a person
and put a film on the other side of them a shadow is produced of the inside of their body.

Bone- high absorption (white)
Tissue- somewhere in the middle absorption (grey)
Air- low absorption (black)
