What happens when a tuning fork is filled with wax?
Ans: We know that the frequency of a tuning fork refers to the number of times it oscillates or vibrates per second. On  applying the wax, the vibrating ends of the tuning fork become much heavier and as such movement is restricted partially. Therefore, the vibrations per second go down hence there is a gradual lowering of the frequency.
