In a Young's double slit experiment, the slit separation d is 0.3 mm and the screen distance D is 1 m. A parallel beam of light of wavelength 600 nm is incident on the slits at angle α as shown in figure. On the screen, the point O is equidistant from the slits and distance PO is 11.0 mm. Which of the following statement(s) is/are correct?
[Adv. 2019]
(a) For α=0, there will be constructive interference at point P.
(b) Fringe spacing depends on α.
(c) For α=π0.36 degree, there will be destructive interference at point P.
(d) For α=π0.36 degree, there will be destructive interference at point O.
