Answer:
Time period T is the time taken by a wave to travel the distance between two successive crests or troughs.
Also the distance between two successive crests and troughs is the wavelength, λ.
Here , given λ=80m and wave velocity, v=20m/s
If f be the frequency of wave so v=fλ and also f=
T
1
Thus, T=
v
λ
=
20
80
=4s
Therefore, the crest will occur in every 4 second time interval.
