A repeating disturbance or movement that transfers energy through matter or space.
A wave that can only travel through matter.
A wave for which the matter in the medium moves back and forth at right angles to the direction the wave travels; has crests and troughs.
A wave for which the matter in the medium moves back and forth along the direction that the wave travels.
The distance between one point on a wave and the nearest point just like it.
The number of wavelengths that pass a fixed point each second; expressed in hertz (Hz).
Speed (in m/s) = frequency (in Hz) * wavelength (in m)
The amount of sound, light, or heat that is thrown back, or reflected.
The bending of a wave as it changes speed in moving from one medium to another.
The maximum distance a wave causes the particles in a medium to move from the rest position.
The highest points on a transverse wave.
The lowest points on a transverse wave.
The least dense regions of a compressional wave.
The most dense regions of a compressional wave.
The matter in which a wave travels.
