A sonometer wire of length `l` vibrates in fundamental mode when excited by a tunning fork of frequency 416 Hz. If the length is double keeping other things same the string will

A

vibrate with a frequency of `416 Hz`

B

vibrate with a frequency of `208 Hz`

C

vibrate with a frequency of `832 Hz`

D

stop vibrating

Text Solution

Verified by Experts

The correct Answer is:
A
In both cases , the 'applied frequency ' is same . So , the frequency of vibration has to be same . However , the mode of vibration of the string be different .

A tuning fork of frequency 256 Hz produces 4 beats per second with a wire of length 25 cm vibrating in its fundamental mode. The beat frequency decreases when the length is slightly shortened. What could be the minimum length by which the wire be shortened so that it produces no beats with the tuning fork ?

In a sanometer experiment, resonance is obtained whth the experimental wire has a length of 21 cm between the bridges and the vibrations are excited by a tunning fork of frequency 256 Hz. If a tuning fork of frequency6 384 Hz is used, what should be the lenght of the experimental wire to get the resonance.

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is
