STANDARD Physics Wave Speed MCQ Question

Type: MCQ-numerical-Medium-Class 11

Figure given shows a sinusoidal wave on a string. If the frequency of the wave is 150 Hz, what is the velocity and wavelength of the given wave?

Question diagram
A

60 m/s, 0.4 m

B

75 m/s, 0.5 m

C

90 m/s, 0.6 m

D

45 m/s, 0.3 m

Correct Answer

Option B

Detailed Explanation

The velocity of a wave is given by v = fλ, where f is the frequency and λ is the wavelength. Given f = 150 Hz and λ = 0.5 m, the velocity v = 150 Hz × 0.5 m = 75 m/s.
