a: visible light ~
b: tennis balls
What:
"An analogy I like is that your body is like a chain link fence. Visible light is like tennis balls - they are big and hit the fence but bounce off. Gamma rays are like bullets from a gun - they are tiny and often pass through without hitting anything, but they are very energetic and if they hit something they will destroy it."
