Assertion : When two tuning forks are vi...

Assertion : When two tuning forks are vibrating with frequencies 256 Hz and 480 Hz are held near each other, beats cannot be heard.
Reason : The principle of super position is valid if the frequencies of the oscillators are nearly equal.

A

Both assertion and reason are true and reason is the correct explanation of the assertion

B

Both assertion and reason are true and reason is not the correct explanation of the assertion

C

Both assertion and reason are false

D

Assertion is true and reason is false

Text Solution

Verified by Experts

The correct Answer is:
D

The beats can be heard only if the difference in the frequecies of two source do not exceed 10 Hz.

Two identical tuning forks vibrating at the same frequency 256 Hz are kept fixed at some distance apart. A listener runs between the forks at a speed of 3.0 m s^-1 so that he approaches one tuning-fork and recedes from the other. find the beat frequency observed by the listener. Speed of sound in air = 332 m s^-1 . .

A tuning fork A frequency 384Hz gives 6 beats in 2 seconds when sounded with another tuning fork B. What could be the frequency of B?

When two tuning forks A and B are sounded together, 4 beats per second are heard.The frequency of the fork B is 384 Hz. When one of the prongs of the fork A is filled and sounded with B, the beat frequency increases, then the frequency of the fork A is:

A tuning fork of frequency 512 Hz makes 4 beats per second with the vibrating string of a piano. The beat frequency decreases to 2 beats per sec when the tension in the piano string is slightly increased. The frequency of the piano string before increasing the tension was:
