A very thin transparent film of soap solution (thickness` to` 0) is seen under reflection of white light. Then the colour of the film appear to be :

Colours thin films are due to

A thin film is viewed in white light. The colour of the film seen at a particular point depends upon:

The colours seen in the reflected white light from a thin oil film are due to

The colours seen in the reflected white light from a thin oil film are due to

Refractive index of a thin soap film of a uniform thickness is 1.34. Find the smallest thickness of the film that gives in interference maximum in the reflected light when light of wavelength 5360 Å fall at normal incidence.
