Choose the definition of amplitude

• The number of complete waves that pass per second

• The distance from the peak of one wave to the peak of an adjacent wave.

• The distance from the equilibrium position of a peak plus the same distance from a trough.

• The maximum distance from the equilibrium position of any point on a wave

Select the formula for finding the wavelength of a wave.

• v = f λ

• λ / v = f

• v f = λ

• λ / f = v

Define frequency.

• the number of wave crests passing a point in one second.

• the numbers of waves in total.

• the height of the waves times each second.

• the speed of waves over time.
