Question

1. (ab f ab f −+ − +− = 25 256 ) ( ) __________​

Answer 1

As tension is increased in string frequency of string will increased and as frequency increases beats decreases of fork frequency is greater than frequency of string

So, beat= frequency of fork − frequency of string

δ=256−f

s

Here f

s

is 5,

∴δ=(256−5)Hz
