4-2 Theory of Light Unit 4: Properties of Matter and the Analysis of Glass
2
Dispersion Dispersion is the process of separating light into component colors.
3
Prism Each color of light corresponds to a different range of frequencies or wavelengths of light.
4
Light wavelength Light rays of one color bend to a different degree of rays of all other colors.
6
Refraction Refraction is the bending of light waves because they change in velocity.
7
Spectra Continuous Spectrum Forensic scientists have learned to characterize different chemical substances by the type and quantity of light they absorb.
8
Radiation As long as electromagnetic radiation is moving through space, its behavior can be described as that of a continuous wave.
9
Absorption Once radiation is absorbed by a substance, the model of light as a stream of discrete particles must be invoked to describe the behavior.
