Question

Calculate the wave length of a water wave with a speed of 20 m/s and a frequency of 2.5 Hz

A. 2
B. 5
C. 8
D. 12​

Answer 1

Wavelength of the water wave is 8 m

Step-by-step explanation:

• Wavelength measures the distance between two successive crests or troughs of the wave. It is given by the following equation

λ = v/f, where f is the frequency, v is the velocity of the wave

Here, v = 20 m/s and f = 2.5 Hz

⇒ λ = 20/2.5

= 8 m
