Document Summary
Electromagnet radiation: has energy made by electric + magnetic fields that increase and decease in intensity as they move through space. Wave prop of electromagnetic radiation described by 3 variables and 1 constant: frequency (v): the number of cycles a wave does per second (s-1/hz) Shorter y = higher freq/longer y = higher freq: wavelength (m): the distance between any point on a wave and the corresponding point on the next crest/trough) Aka, the distance the wave travels during one cycle: speed(m/s): the distance it moves per under time. In a vacuum, er moves at the speed of light: 3. 00 x 108m/s. C = v x y , since product of v and y are constant, relationship = reciprocal. V y and v y: amplitude: height of the crest, related to intensity of radiation (brightness of light) Light of a certain color has a specific frequency (dimmer at low amp, brighter at high amp)
