Question
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:

  1. $\text{v}$

  2. $\frac{\text{v}}{2}$

  3. $2\text{v}$

  4. $\sqrt{2}\text{v}.$

✓

Answer

  1. $\text{v}$

Explanation:

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.
