Answer 1

Answer:

Phase Difference is used to describe the difference in degrees or radians when two or more alternating quantities reach their maximum or zero values. Previously we saw that a Sinusoidal Waveform is an alternating quantity that can be presented graphically in the time domain along an horizontal zero axis.

Phase epoch is the initial phase of a vibrating particle at time,t = 0. Phase difference is the difference, expressed in degrees or radians, between two waves having the same frequency and referenced to the same point in time
