A monochromatic parallel beam of light of wavelength 
is incident normally on the plane, containing slits 
and 
. The slits are made of unequal width so that the intensity due to one slit on screen is four times that of the other slit. The screen is placed along 
-axis, as shown in the figure. The distance between slits is d and between the screen and slits is 
.
Column I | Column II | ||
(I) | The distance between two points on the screen having equal intensities, such that intensity at those points is of maximum intensity. | (A) | |
(II) | The distance between two points on the screen having equal intensities, such that intensity at those points is of maximum intensity. | (B) | |
(III) | The distance between two points on the screen having equal intensities, such that intensity at those points is of maximum intensity. | (C) | |
(IV) | The distance between two points on the screen having equal intensities, such that intensity at those points is of maximum intensity. | (D) |
