367768 A narrow monochromatic beam of light of intensity \({I}\) is incident on a glass plate as shown in figure. Another identical glass plate is kept close to the first one and parallel to it. Each glass plate reflects \({25 \%}\) of the light incident on it and transmits the remaining. Find the ratio \(\sqrt {\frac{{{I_{\max }}}}{{{I_{\min }}}}} \) the interference pattern formed by two beams obtained after one reflection at each plate.

367769 Assertion :
When monochromatic light is incident on a surface separating two media, the reflected and refracted light both have the same frequency as the incident frequency.
Reason :
The frequency of monochromatic light depends on media.

367770 Colours of thin films results from

367771 Assertion :
Thin films such as soap bubble or thin layer of oil on water show beautiful colours when illuminated by white light.
Reason :
It happens due to the interference of light reflected from the upper surface of the thin film.
