Answer:
Time period = 11.6 seconds
frequency = 0.0862 Hz
wave velocity = 2.586 m/s
Explanation:
Five crests passes in 58 seconds
Time period, t = 58 / 5 = 11.6 seconds
The wavelength is defined as the distance between two consecutive crests.
So, wavelength, λ = 30 m
So,
Frequency = reciprocal of time period = 1 / 11.6 = 0.0862 Hz
wave velocity, v = f x λ
v = 0.0862 x 30 = 2.586 m/s
The correct answer would be D.
