A wave is given by $y = 3\sin 2\pi \left( {\frac{t}{{0.04}} - \frac{x}{{0.01}}} \right)$, where $y$ is in $cm$. Frequency of wave and maximum acceleration of particle will be
  • A$100\,Hz,\;4.7 \times {10^3}\,cm/{s^2}$
  • B$50\,Hz,\;7.5 \times {10^3}\,cm/{s^2}$
  • C$25\,Hz,\;4.7 \times {10^4}\,cm/{s^2}$
  • D$25\,Hz,\;7.4 \times {10^4}\,cm/{s^2}$

    A string fixed at both ends is in resonance in its $2^{nd}$ harmonic with a tuning fork of frequency $f_1$. Now its one end becomes free. If the frequency of the tuning fork is increased slowly from $f_1$ then again a resonance is obtained when the frequency is $f_2$. If in this case the string vibrates in $n^{th}$ harmonic then
