A sonometer wire is in tnison with a tuning fork of frequency 256 Hz, when the lenghts of the wire between the bridges is 75 cm and only one loop is formed. By keeping the lengths and tension constant, the wire is made to vibrate with 2 loops. The wire can still be in resonance with a tuning fork, provided the freqency of the tuning fork is

100 Hz

512 Hz

384 Hz

128 Hz

Text Solution

Verified by Experts

The correct Answer is:

For two loops, the frequency will be 2n
` :. ` frequency of tuning fork will be ` 256 xx 2 = 512 ` Hz
