Answer:
Given:
Linear density of stretched string is increased by 1%.
To find:
Change in frequency of string.
Concept:
Due to change in linear density of a string , it leads to change in the velocity of the transverse pulse (wave) .
Now changes in the Velocity of the wave leads to changes in the fundamental frequency of the standing wave.
Calculation:
Let linear density be μ.
Velocity of wave is given as :
So fundamental frequency will be :
So for small changes in μ , we can say that :
So final answer :

We Know That :
For Small Values :
So Change In Fundamental Frequency Of String Is 0.5%
