When a tuning fork is marked as 512 Hz, oscillator reading is 514. The beat are heard, so the frequency of the tuning fork is 514 ± 2 =516 or 512. When the oscillator reading is obtained as 510 Hz. The frequency of tuning fork is 510 ± 6=516 or 504. The common value is 516 Hz. Therefore the frequency of tuning fork is 516 Hz.
