Assertion : Where two vibrating tuning forks having frequencies \(256\;Hz\) and \(512\;Hz\) are held near each other, beats cannot be heard. Reason : The principle of superposition is valid only if the frequencies of the oscillators are nearly equal.
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.
Explanation:
Beats will not be heard when the frequencies of the tuning forks are \(256\;Hz\) and \(512\;Hz\) because they are not close enough in frequency for distinct beats to form. However, the reason is false because the principle of superposition is valid for a wide range of frequency differences. So correct option is (3).

When a guitar string is sounded with a \(440\;Hz\) tunning fork, a beat frequency of \(5\;Hz\) is heard. If the experiment is repeated with a tuning fork of \(437\;Hz\), the beat frequency is \(8\;Hz\). The string frequency \((Hz)\) is :
1 435
2 445
3 448
4 429
Explanation:
When 5 Beats are heard with \(440\,Hz\) then guitar may have \(435\,Hz\) or \(445\,Hz\) frequency for 2nd tuning fork of \(437\,Hz\) is used and 8 beats are heard this condition is satisfied if guitar's frequency is \(445\,Hz\).

5 beats/s are produced on blowing together two closed organ pipes of the same diameter but of different lengths. If shorter pipe is of \(10\;cm\) length and speed of sound in air is \(300\;m{\rm{/}}s\), length of other pipe is
