Homework Statement
the correct ans is A. but my ans is D.
When the thin polaroid is placed in front of S1 , it slow down the light wave . as v = fλ. as v decreases , λ also decreases. This cause the x ( fringe separation ) to be smaller. And this also cause the light ray to conccentrate on the ' bright region' which has smaller area comapred to before. Thus, the intensity of bright fringes is higher. i can't undrstand why the central maximum is shifted towars P. Correct me if i am wrong. Thank in advance!
