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

Colours thin films are due to

If white light is used in the Newton’s rings experiment, the colour observed in the reflected light is complementary to that observed in the transmitted light through the same point. This is due to

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 :

What is the minimum thickness of a thin film required for constructive interference in the reflected light from it ? Give, the refractive index of the film = 1.5 wavelength of the light incident on the film = 600 nm

Assertion: The colour of the oil film on the surface of water continuously changes. Reason: The colour of the light reflected by the oil film depends upon its thickness.

Statement I: Thin films such as soap bubble or a thin layer of oil on water show beautiful colors when illuminated by white light. Statement II: It happens due to the interference of light reflected form the upper surface of thin film.
