Assertion : Where two vibrating tuning f...

Assertion : Where two vibrating tuning forks having frequencies `256 Hz` and `512 Hz` are held near each other, beats cannot be heard.
Reason : The princile of superposition is valid only if the frequencies of the oscillators are nearly equal.

A

Statement -1 is true, Statement-2, Statement -2 is correct explanation of statement-1.

B

Statement-1 is true, Statement-2 is true, Statement-2 is not a correct explanantion of Statement-1.

C

Statement-1 is correct, Statement-2 is false.

D

Statement-1 is false, Statement-2 is true.

Text Solution

Verified by Experts

The correct Answer is:
a
Number of beats `//` sec `=512-256=256. ` They cannot be distinctly heard because of the property of persistence of hearing. Statement-2 is false.
