Concept:

Wave: 

The propagation of disturbance caused in a medium or electromagnetic field is termed as a wave. When waveforms consecutive crests and Troughs are formed.

Frequency of wave (ν): 

The number of oscillations made by the wave in one second is known as the Frequency of wave. One oscillation is defined when one complete cycle of crest and trough is completed. 

The wavelength of wave (λ): 

The distance between two consecutive crests or two consecutive troughs is called the wavelength. 

Calculation:

Given:

As per the given diagram total cycle = 2.5

Distance of the cycle = 20 cm.

The velocity of wave:
