# Question #2148b

##### 1 Answer

Given that the velocity of stationary wave produced in a stretched string depending on its tension (T)and its mass per unit length (m) is

As shown in above figure the wave lengths

For first i th harmonic

where

For 1st harmonic wave length

For 2nd harmonic wave length

For 3rdharmonic wave length

So

For 1st harmonic, frequency

For 2nd harmonic, frequency

For 3rd harmonic, frequency
