8 CK Sound Waves

8 CK SCIENCE Sound Waves - COMPLETE

TermDefinition
Wavelength the distance between two consecutive identical points on a wave
Frequency the number of complete waves (or cycles) per unit of time
Amplitude the maximum movement from rest (measured from rest to a crest OR a trough)
Crest the highest point of a wave (analogous to compression)
Trough the lowest point of a wave (analogous to rarefaction)
Transverse Wave a wave in which the motion of the medium is at right angles to he direction of the wave (EM waves)
Longitudinal Wave a wave in which the motion of the medium is parallel to the direction of the wave (sound)
Wave a traveling disturbance that carries energy from one place to another
Vibration Any movement that follows the same path repeatedly
Medium the matter or substance through which a wave is transmitted
Wave Speed how fast waves move (_________ = frequency x wavelength)
Wave Interactions when two or more waves meet and affect each other
Reflection waves bounce off of surfaces
Refraction waves change directions (bend) when they pass from one medium to another of differing densities
Diffraction waves change directions (bend) when they pass through an opening or around a barrier
Constructive Interference two or more waves meet and add together to make a larger wave
Destructive Interference two or more waves meet and add together to make a smaller wave
