355003 Two sitar strings \(A\) and \(B\) playing the note ' \(Ga\) ' are slightly out of tune and produce beats of frequency \(6\,Hz\). The tension in the string \(A\) is slightly reduced and the beat frequency is found to reduce to \(3\;Hz\). If the original frequency of \(A\) is \(324\;Hz\), what is the frequency of \(B\) ?

1 \(518\;Hz\)
2 \(218\;Hz\)
3 \(318\;Hz\)
4 \(418\;Hz\)

355004 When two tuning forks \(A\) and \(B\) are sounded together \(x\) beat/s are heard. Frequency \(A\) is \(n\). Now, when one prong of \(B\) is loaded with a little wax, the number of beats/s decreases. The frequency of fork \(B\) is

1 \(n-x\)
2 \(n+x\)
3 \(n-2 x\)
4 \(n-x^{2}\)
PHXI15:WAVES

355005 To hear beats, it is essential that the two sound waves in air should

1 Be travelling in opposite directions
2 Be travelling in the same direction
3 Have slightly different amplitude
4 Have slightly different frequencies
PHXI15:WAVES

355006 Two lines of frequency \(n_{1}\) and \(n_{2}\) are sounded together. The beats can be heard distinctly when

1 \(20>\left(n_{1}-n_{2}\right) < 30\)
2 \(30 < \left(n_{1}-n_{2}\right)>40\)
3 \(0 < \left(n_{1}-n_{2}\right) < 10\)
4 \(50 < \left(n_{1}-n_{2}\right) < 100\)
