Question

White light is used to illuminate the two slits in Young’s double slit experiment. The separation between the slits is d and the distance between the screen and the slit is D (>> d). At a point on the screen directly in front of on the slits, certain wavelengths are missing. The missing wavelengths are (here m = 0, 1, 2, … is an integer)     

Solution

Correct option is

 

The distance of the mth minimum from the centre of the screen is given by             

                                      

For a point on the screen directly in front of one of the slits,

y = d/2. Hence, for minima (zeros) of intensity, we have
