A light ray of wavelength 5000A° travelling through a medium of refractive index 1.5 gets incident at an angle of 30° on another medium of refractive index 1.25 and thickness 0.2mm. Calculate the minimum phase difference and path difference between the rays coming back into the initial medium from the two faces of the second medium....
