STANDARD Physics Wave Speed MCQ Question
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?
60 m/s, 0.4 m
75 m/s, 0.5 m
90 m/s, 0.6 m
45 m/s, 0.3 m
Correct Answer
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.
