Question

When a tuning fork vibrates, the vibrations of
its two prongs have a phase difference of
(a) ???? (b) ???? /2
(c) Zero (d) 2 ????

Answer 1

Answer: Zero

Explanation:

When a tuning fork vibrates, the vibrations of it's two prongs will have a phase difference of Zero.

Phase Difference is the difference between two sinusoidally varying quantities that have the same frequency, measured either as an angle or a time.

When a tuning fork vibrates the two sinusodially varying quantities does not have any difference and hence the phase difference is Zero.
