In a Young’s double slit experiment a monochromatic light whose wavelength is l strikes on the slits, separated by distance d, as shown in the figure. Refractive index of the medium between slits and screen varies with time t as n = n0 + kt. Here n0 and k are positive constants. Position of any point P on screen is measure by its y-coordinate as shown.
