MCQ
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:
  • $\text{v}$
  • B
    $\frac{\text{v}}{2}$
  • C
    $2\text{v}$
  • D
    $\sqrt{2}\text{v}.$

Answer

Correct option: A.
$\text{v}$
The boat transmits the same wave without any change of frequency to cause the cork to execute SHM with same frequency though amplitude may differ.
