Wave Medium

the bouncing back of a wave when it hits a surface through which it cannot pass

​

​reflection

the bending of a wave as it passes at an angle from one medium to another

​refraction

the transfer of energy from light waves to particles of matter

​absorbtion

the speed at which a wave travels through a medium

​wave speed

the material through which a wave travels

(solid, liquid, gas)

medium

the tones highness or lowness; depend on frequency

pitch

the number of complete wavelengths that pass a point in one second, measured in Hertz (Hz)

frequency

the distance between tow crests or two troughs of a wave, measured in

meters (m)

wavelength

the height of a wave measured from a center line to the crest or through

amplitude

wave that moves the medium in a direction parallel to the direction in which the wave travels (sound)

longitudinal wave

wave in which the particles move perpendicularly to the direction the wave is traveling (light, water)

transverse wave
