Option A is correct. Phase difference describes the difference in the phase angle between any two waves at any given position along the waves.
What is phase difference?
The time difference between the identical points inside the wave cycles of the two sounds the peaks or positive-going zero crossings,
If we defined it as a fraction of one wave cycle determines the phase difference between two sound waves of the same frequency traveling past a fixed location.
The two waves are taken into consideration;
Wave 1
[tex]\rm y_1 = Asin(\omega t)[/tex]
Wave 2
[tex]\rm y_2= Asin (wt+\phi)[/tex]
[tex]y_2-y_1= \phi[/tex]
[tex]\phi[/tex] is the phase difference.
Phase difference describes the difference in the phase angle between any two waves at any given position along the waves.
Hence Option A is correct.
