354995 A tuning fork \(A\) produces 4 beats \(s^{-1}\) with another tuning fork \(B\) of frequency \(320\;Hz.\) On filling one of the prongs of \(A, 4\) beats \(s^{-1}\) are again heard when sounded with the same fork \(B\). Then, the frequency of the fork \(A\) before filling is

1 \(328\;Hz\)
2 \(316\;Hz\)
3 \(324\;Hz\)
4 \(320\;Hz\)

354996 Two tuning forks, \(A\) and \(B\), produce notes of frequencies \(256\;Hz\) and \(262\;Hz\). An unknown note sounded with A produces certain beats. When the same note is sounded with \(B\), the beat frequency gets doubled. The unknown frequency is

1 \(250\;Hz\)
2 \(252\;Hz\)
3 \(254\;Hz\)
4 \(256\;Hz\)

354997 Two identical flutes produce fundamental notes of frequency \(300\;Hz\) at \(27^\circ C\). If the temperature of air in one flute is increased to \(31^\circ C\), the number of the beats heard per second will be

354998 At a point, beat frequency of \(n\;Hz\) is observed. It means:

1 Amplitude of vibrations changes simple harmonically with frequency \(n/2\;Hz\)at that point only
2 Medium particles, at that point, are vibrating with frequency \(n\,Hz\)
3 At that, zero intensity is observed \(2 n\) times per second
4 None of the above
