X-rays

electromagnetic waves (short-wavelength and high frequency) wavelength is roughly the same size as the diameter of an atom.
Used in Hospitals: 1. to make images and CT scans 2. to destroy tumors at or near the body surface.
can damage living tissue when they pass through it
are absorbed more by bones and teeth (denser materials) than they are by soft tissue
brighter bits on an x-ray are where fewer x-rays get through - shows denser material (bones/teeth)
x-ray images can be formed electronically - CCDs (Charge-coupled devices) CCDs: small silicon chips, divided up into a grid of millions of identical pixels. Detect x-rays and produce electronic signals used to form…
