When tuning forks A and B are sounded to...

When tuning forks A and B are sounded together, 20 beats are produced in 8 second between them. (i.e. beat frequency is `(20)/(8) =2.5 Hz).` Now, when some wax is applied on one of these tuning forks, 32 beats are produced in 8 s. If frequency of that fork on which wax is not applied is 512 Hz then find frequency of another tuning fork, before and after applying wax.

Before appliying wax `514.5 Hz OR 509.5 Hz` and after applying wax 508 Hz
