Which term describes the number of troughs that pass a point in a given amount of time?

wave speed

wavelength

period

frequency

Frequency

Explanation:

A transverse wave has crests and troughs. one trough and one crest form a wave. A wave can be described by its wavelength, frequency, period and speed.

Frequency (f) can be defined as the number of waves or crests or number of troughs that pass a point per unit second. It can be measured in Hertz (Hz) or 1/s.

Wavelength (λ) is the distance between two consecutive crests or troughs.

Period is the inverse of frequency.

T = 1/f

Product of wavelength and frequency gives the speed of the wave.

v = λ f
