Why is thin film interference important?
Thin-film Interference Soap Bubble It takes place at the upper boundary of the film. The shift occurs mainly because of the lower refractive index of the air than that of the film. Further, light from the upper air-film interface will keep moving to the lower film-air interface where it is reflected.

What is the thickness of thin-film?
One should not be uncertain that “thin” films can be thicker than “thick” films. The thickness of thin-film material may be few nanometers to about several micrometers for a specific application. The thickness may be few atoms onto a “substrate” surface or on some other layer already deposited.
How is thickness of thin-film determined?
The thickness of a single-layer film can be measured easily using a spectrophotometer. Note, however, that this is possible only for film thickness in a range of approximately 0.3 to 60 μm, and that the refractive index of the film material is required for measurement.
