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 $$\alpha$$ 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?

A

For $$\alpha = \frac{0.36}{\pi}$$ degree, there will be destructive interference at point O.

B

For $$\alpha = 0$$ there will be constructive interference at P point P.

C

For $$\alpha = \frac{0.36}{\pi}$$ degree, there will be destructive interference at P point P.

D

Fringe spacing depends on $$\alpha$$.
