Question:

What are the names of the distance between two consecutive crests (or trough) on a wave, how long it takes to observe the two, and how many of these move in per unit time?

a) period, wavelength, frequency

b) wavelength, period, frequency

c) frequency, wavelength, period

d) frequency, period, wavelength

e) wavelength, velocity, frequency

Wave Characteristics:

The parameters that help us aptly explain any wave are the period, wavelength, frequency, amplitude, and speed of the wave. The crests, troughs, and displacement of waves help give context and definition to the parameters of a wave.
