PhysicsEasysingle choice

$n$ number of waves are produced on a string in 0.5 second. Now the tension in the string is doubled (Assume length and radius constant), the number of waves produced in 0.5 second for the same harmonic will be

Options:

Answer:

Solution:

$n = \frac{1}{2 L} \sqrt{\frac{T}{m}}$

$n^{'} = \frac{1}{2 L} \sqrt{\frac{2 T}{m}}$

$= \sqrt{2} \frac{1}{2 L} \sqrt{\frac{T}{m}}$

$n^{'} = \sqrt{2} n$
