In a Young's double slit experiment, the slit separation d is 0.3 mm and the screen distance D is 1m. A parallel beam of light of wavelength 600nm 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?
  • a)
    For  degree, there will be destructive interference at point O
  • b)
    Fringe spacing depends on α
  • c)
    For  degree, there will be destructive interference at point P
  • d)
    For α = 0, there will be constructive interference at point P
Correct answer is option 'C'. Can you explain this answer?

(1) Δx = dsinα
= dα  (as α is very small) 

so constructive interference


= 3 × 10–4 (2 × 10–3 + 11 × 10–3)
= 39 × 10–7


= 33 × 10–7
