A tuning fork having n = 158 Hz, produce 3 beats/s with another. As we file the arm of unknown, beats become 7 then calculate the frequency of unknown.

Text Solution

Verified by Experts

The frequency of unknown tuning fork should be `158 pm 3 = 155 Hz or 161 Hz`
After filling the number of beats = 7 so frequency of unknown tuning fork should be
`158 pm 7 = 165 Hz or 151 Hz`
As both above frequency can be obtain by filling so frequency of unknown `= 151//161 Hz`
