Consider a plane beam of light is falling normally on a material with thickness (d) and refractive index (n), the light partially transmits and partially reflects the light, so the light transmitting the light travels a distance (2nd) coming out of the material have a phase change of ∏ always, How? will it be different for different thickness?
If no why the phase change can't be ∏/2 or 2∏ or something else?
