A tuning fork A, marked 512 Hz, produces 5 beats per second,

When the tuning fork B is loaded with the wax, the frequency of the tuning fork becomes less than its original frequency. When the tuning fork is marked 512 Hz, let’s

assume that the tuning fork B is marked to 517 Hz because it produces 5 beats per second and when it is loaded, the frequency is less than 512 Hz. So it can be said

that when the tuning fork is not loaded, the frequency remains the same that is 517 Hz.
