# The young’s double slit experiment is done in a medium of refractive index 4/3. A light of 600 nm wavelength is falling on the slits having 0.045 mm separation. The lower slit S2 is covered by a thin glass sheet of thickness 10.4 ?m and refractive index screen placed 1.5 m front the slits as shown.
