In an experiment with sonometer, a tuning fork of frequency 256 Hz resonates with a length of 25 cm and another tuning fork resonates with a length of 16 cm. Tension of the string remaining constant, the frequency of the second tuning fork is –

A

163.84 Hz

B

400Hz

C

320Hz

D

204.8Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n_2l_2 = n_1l_1`
`n_2 = (n_1l_2)/(l_2) = (256xx25)/(16) = 4000 Hz`
