|
Term
| characteristics of x-rays |
|
Definition
Invisible ionizing photons
No mass or charge
Travel in a waveform at the speed of light
Travel in a straight but diverging path
Cannot be focused
Highly penetrating
Poly-energetic
Energy is related to frequency
Higher frequency = greater energy = greater penetration
Can cause fluorescence of certain crystals |
