Answer Key : (c) -

(c)

Suppose slit width’s are equal, so they produces waves of equal intensity say . Resultant intensity at any point  where  is the phase difference between the waves at the point of observation

For maximum intensity     …(i)

If one of slit is closed. Resultant intensity at the same point will be  only,     …(ii)

Comparing equations (i) and (ii) we get
