Question

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

Answer 1

Answer:

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, $y=A\ sin(\omega t)$

Wave 2, $y=A\ sin(\omega t+\phi)$

Where

A is the amplitude of wave

$\omega$ is the angular frequency

$\phi$ is the phase difference between two waves

If $\Delta d$ is the path difference, it is given by :

$\Delta d=d\ sin\theta$

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