A sound wave of frequency $\mathrm{v} \mathrm{Hz}$ initially travels a distance of $1 \mathrm{~km}$ in air. Then, it gets reflected into a water reservoir of depth $600 \mathrm{~m}$. The frequency of the wave at the bottom of the reservoir is
$$
\text { ( } V_{\text {air }}=340 \mathrm{~m} / \mathrm{s} V_{\text {water }}=1484 \mathrm{~m} / \mathrm{s} \text { ) }
$$

Options:
  • A $>v \mathrm{~Hz}$
  • B $ < v \mathrm{~Hz}$
  • C $v \mathrm{~Hz}$
  • D 0 (the sound wave gets attenuated by water completely)
Solution:
