Question

A certain wavelength wave of 850 mm travels through the water with a frequency of 660 Hz. Find out the velocity of the wave.

Answer 1

Given:-

• Wavelength, λ = 850 mm = 850/1000 = 0.85 m

• Frequency, v = 660 Hz

To Find:-

• Wave velocity ,u

Solution:-

As we know that wave velocity is defined as the product of wavelength and frequency.

• u = λv

where,

u is the wave velocity

λ is the wavelength

v is the velocity of wave.

Substitute the value we get

➨ u = 0.85 × 660

➨ u = 561 m/s

Therefore, the wave velocity is 561 m/s.

Answer 2

=> Wave velocity = Frequency × wave length

=> Wave velocity = 850/1000 × 660

=> Wave velocity = 0.85 × 660

=> Wave velocity = 561 m/s

Wave velocity is 561 m/s.
