Can u pls solve another question of mine https://www.sarthaks.com/1059395/solve-question-given-in-the-image

dude if u hav a normal sin wave starting at origin , phase diff will be zero . now if u shift this same sin wave a distance of t/2 , phase diff will correspond to t/2 . and since t gives 2pi (one cycle), t/2 will give half of that which is pi.
