Physics - Wave Optics Question with Solution | TestHub
Column I shows four situations of standard Young's double slit arrangement with the screen placed far away from the slits and . In each of these cases , and , where is the wavelength of the light used. In the cases and , a transparent sheet of refractive index and thickness is pasted on slit . The thickness of the sheets are different in different cases. The phase difference between the light waves reaching a point on the screen from the two slits is denoted by and the intensity by . Match each situation given in Column-I with the statement(s) in Column-II valid for that situation.

Options:
Answer:
Solution:
(A) Intensity at is maximum. It will continuously decrease from towards . Path difference due to slap will be compensated by geometrical path difference. Hence, . and . When path difference increases from 0 to , intensity will decrease from maximum to zero. Hence, in this case, and In this case
