Front

Define wavelength.

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

Define amplitude.

Back

Amplitude is the maximum distance a wave moves from its rest position.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another.

Front

What is absorption in the context of waves?

Back

Absorption is the process by which a wave's energy is taken up by a material.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave.
