By Zoe, Alexa, Ellie and Selena
What are X-rays?
X-Ray is short for X-Radiation In 1895 German Physicist Wilhelm Rontgen discovered X-rays. He called them x-Rays because the "x" stood for unknown. The X-ray is an electromagnetic wave of high energy and very short wave length,which allows it to pass through many materials Some examples of xrays are: Mammography Medical CT Airport Secuity Luggage checks
How does an X-ray work?
An X-Ray is basically a giant camera that lets us see through things. An X-Ray projects electromagnetic waves, which are more energetic, this is why it lets us see through different materials. Bone, fat, muscle and tumors absorb X-Rays at differet levels. These X-rays allow us to see all of these things on the one photo.
