Select the statement that correctly completes the description of phase difference.

phase difference describes

the difference in the phase angle between any two waves at any given position along the waves.

the shift between the positions of corresponding crests of two waves of the same frequency.

the difference in the frequencies of two waves at a given time.

the displacement of a wave particle from its undisturbed p

The difference in the phase angle between any two waves at any given position along the waves.

Explanation:

Phase difference describes  the difference in the phase angle between any two waves at any given position along the waves. The equation of wave is given by :

Wave 1,

Wave 2,

Where

A is the amplitude of wave

is the angular frequency

is the phase difference between two waves

If is the path difference, it is given by :

Hence, the correct option is (a) "the difference in the phase angle between any two waves at any given position along the waves".
