355007 A tuning fork \(A\) produces 5 beats per second with a tuning fork of frequency \(480\,Hz\). When a little wax is stuck to a prong of fork \(A\), the number of beats heard per second becomes 2 . What is the frequency of tuning fork \(A\) before the wax is stuck to it?

1 \(475\;Hz\)
2 \(482\;Hz\)
3 \(478\;Hz\)
4 \(485\;Hz\)

355008 Each of the two strings of length \(51.6\;cm\) and \(49.1\;cm\) are tensioned separately by \(20\;N\) force.Mass per unit length of both the strings is same and equal to \(1g{m^{ - 1}}\). When both the strings vibrate simultaneously, the number of beats is :

1 7
2 4
3 3
4 8
PHXI15:WAVES

355009 Assertion :
To hear different beats, difference of the frequencies of two sources should be less than 10 .
Reason :
More the number of beats more is the confusion.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
