Wave an electrical impulse or radio wave transmitted or received
crest The top of a wave
trough A crest is the point on a wave with the maximum value or upward displacement within a cycle.
amplitude The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
wavelength A wave can be measured between any two points with the same phase, such as between crests
frequency the frequency in hertz meaning the number of cycles per second.
absorption the process or action by which one thing absorbs or is absorbed by another.
reflection the throwing back by a body or surface of light, heat, or sound without absorbing it.
law of reflection The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.
diffraction the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.
interference the combination of two or more electromagnetic waveforms to form a resultant wave in which the displacement is either reinforced or canceled.
