Answer:
The correct option is the option;

Explanation:
The wavelength of a wave is the distance between two successive crests of the wave
Therefore, the wavelength, λ, is given by the fraction of the velocity, <em>v</em>, of the wave divided by the frequency, <em>f</em>, (the number of cycles that pass through a point) of the wave
Mathematically, we have;


Answer:
Amplitude
Explanation:
The amplitude is the vertical distance from the centreline to the crest. The frequency is the number of waves that pass a certain distance in a certain amount of time. The trough is the lowest point of a wave and the wavelength is the distance from one wave to the same point on the other wave.
