Question
In the figure shown in a YDSE, a parallel beam of light is incident on the slits from a medium of refractive index n1. The wavelength of light in this medium is λ1. A transparent slab thickness ′t′ and refractive index n3 is put in front of one slit. The medium between the screen and the plane of the slits is n2.The phase difference between the light waves reaching point O (Symmetrical relative to the slits) is :
Options
A.
(n3 - n2) t
(n3 - n2) tB.
(n3 - n2) t
(n3 - n2) tC.
t
tD.
