354999 Two vibrating tuning forks produce progressive waves \({y_{1}=4 \sin (500 \pi t)}\) and \({y_{2}=2 \sin (506 \pi t)}\). These tuning forks are held near the ear of a person. The person will hear \({\alpha}\) beats/s with intensity ratio between maxima and minima equal to \({\beta}\). Find the value of \({\beta-\alpha}\).

355000 A tuning fork produces 6 beats/sec with sonometer wire when its tensions are either \(169\,N\) or \(196\,N\). The frequency of that fork is

1 \(162\;Hz\)
2 \(190\;Hz\)
3 \(200\;Hz\)
4 \(80\;Hz\)
PHXI15:WAVES

355001 Ten tuning forks are arranged in increasing order of frequency in such a way that any two nearest tuning forks produce 4 beats/sec. The highest frequency is twice of the lowest. Possible highest and the lowest frequencies are

1 80 and 40
2 100 and 50
3 44 and 22
4 72 and 36
PHXI15:WAVES

355002 Two tuning forks \(P\) and \(Q\), when set vibrating, gives 4 beats/s. If a prong of the fork \(P\) is waxed, the beats are reduced to 2 per second. If frequency of \(Q\) is \(250\;Hz\), then frequency of \(P\) before filing is

1 \(246\;Hz\)
2 \(254\;Hz\)
3 Any of (1) & (2)
