|---|
| thermal energy | sum of kenitic energy and potential energy of system of particles |
| incandescent light | light generated by heating piece of metal til it glows |
| florescent light | light generated by using phosphors to convert untraviolet radiation to visible light |
| coherent light | light of only one wavelength in one direction, constant distasnce between crests |
| incoherent light | light - multiple wavelengths, multiple directions, multiple crests of waves |
| interference | occurs when two or more waves overlap and form new wave |
| linearly polarized light | light with magnetic field vibrates one direction |
| holography | produces three-dimensional image of object |
| total internal reflection | complete reflection of light at boundary between two materials |
| optical scanner | device reads intensities of reflected light and converts to digital |
