367763 An oil flowing on water seems coloured due to interference. For observing this effect, the approximate thickness of the oil film should be

367764 A ray of light of intensity \({I}\) is incident on a parallel glass-slab at a point as shown in the figure. It undergoes partial reflection and refraction. At each reflection \({\rm{20\% }}\) of incident energy is reflected. The rays \({A B}\) and \({A^{\prime} B^{\prime}}\) undergo interference. The ratio \({I_{\text {max }} / I_{\text {min }}}\) is

367765 What is the minimum thickness of a thin film required for constructive interference in the reflected light from it ?
Given, the refractive index of the film \( = {\rm{ }}1.5,\) wavelenth of the light incident on the film\( = 600\,nm.\)

367766 Assertion :
The colours of the film is dependent on the thickness of film and wavelength of the light.
Reason :
If a thin soap film is arranged vertically. the spectrum of coloured fringes are spread equally on the film.

367767 Assertion :
Colours are seen in thin layers of oil on the surface of water.
Reason :
White light is composed of several colours.
