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 ?
Select the correct option:
A
For $\alpha=\frac{0.36}{\pi}$ degree, there will be destructive interference at point $O$.
B
Fringe spacing depends on $\alpha$
C
For $\alpha=\frac{0.36}{\pi}$ degree, there will be destructive interference at point $P$
D
For $\alpha=0$, there will be constructive interference at point P .
