The frequency of tuning fork is 243 Hz.
Explanation:
Given that,
Number of beat = 5
We need to calculate the frequency of tuning fork
Using formula of frequency
Frequency of sonometer wire = frequency of tuning fork energy
If length the wire is reduced by 4% the wire.
We need to calculate the frequency when length the wire is reduced
Where, p = number of loop
T = tension
M = mass
Put the value into the formula
Now, using formula of beat frequency
Put the value into the formula
Hence, The frequency of tuning fork is 243 Hz.
