In a thin-film light reflects
WebWhite light is incident normally on a thin soap film having an index of refraction of 1.34. It reflects with an interference maximum (what is that, can you please explain?) at 684 nm and an interface minimum (and that?) at 570 nm with no minima (???) between those two values. The film has air on both sides of it. What is the thickness of the ... WebLight striking a thin film is partially reflected (ray 1) and partially refracted at the top surface. The refracted ray is partially reflected at the bottom surface and emerges as ray 2. These rays will interfere in a way that depends on the thickness of the film and the indices of refraction of the various media.

http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/interf.html WebThin film interference refers to the phenomenon where interference of the light waves that get reflected by the upper and lower sides of a thin film occurs. This interference is capable of either increasing or reducing the light reflected from the film. How does Thin film interference happening ?
