A cork floating in a calm pond executes simple harmonic motion of frequency v when a wave generated by a boat passes by it. The frequency of the wave is(a) v(b) v/2(c) 2v(d) √2V.

Answer»

The correct answer is (a) v

EXPLANATION: 

The time taken by the wave in moving one wavelength is exactly the same as in moving the cork one oscillation. Hence the frequency of the wave is equal to the frequency of the cork.
