In an experiment with sonometer a tuning fork of frequency 256Hz resonates with a length of 25cm and another tuning fork resonates with a length of 16x\cm. Tension of the spring remaining constant the frequency of the second tuning fork is?

In an experiment with sonometer a tuning fork of frequency 256Hz resonates with a length of 25cm and another tuning fork resonates with a length of 16x\cm. Tension of the spring remaining constant the frequency of the second tuning fork is? Correct Answer 400Hz

v∝1/L v2/v1 = L1/L2 v2=L1/L2 ×v1=25/16×256=400Hz.
