Question | Answer |
---|---|
is a disturbance that carries energy from one place to another without carrying matter | Wave |
waves that require a medium through which to travel | Mechanical waves |
a wave (as a radio wave, wave of visible light, or X-ray) that consists of an associated electric and magnetic fields. Can travel through both a medium and empty space | Electromagnetic wave |
Transverse waves a wave that moves the medium in a direction perpendicular to the direction in which the wave travels | Transverse waves |
a wave that moves the medium in a direction parallel to the direction in which the wave travels | Longitudinal waves |
material through which a wave travels | Medium |
a repeated back-and-forth or up-and-down motion | Vibrations |
the distance between one wave crest and the next (or between one wave trough and the next) | Wavelength |
the number of complete waves or cycles that pass a fixed point in a specific unit of time | Frequency |
the height of the wave ((is half the vertical distance from crest to trough) | Amplitude |
Speed how fast a wave passes through a medium | Speed |
the highest point of a wave | Crest |
the lowest point of a wave | Trough |
the area of a longitudinal wave in which the molecules are the most crowded together | Compression |
the area of a longitudinal wave in which the molecules are the most spread apart | Rarefaction |
