Parts of a Wave

What is the amplitude of a wave?

• The distance between two successive crests or troughs

• The maximum displacement of a point on the wave from its rest position

• The number of cycles per unit time

• The distance over which the wave's shape repeats

If two waves have the same frequency but different amplitudes, how do their speeds compare?

• The wave with the higher amplitude travels faster

• The wave with the lower amplitude travels faster

• They travel at the same speed

• It depends on the wavelength
