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.

A thin film of a specific meterial can be used to decrease the intensity of reflected light. There is destrucive inteference of wave reflected from upper and lower surface of the film. These films are called non-reflecting or anti-reflecting coatings. The process of coating the lens or surface with non-reflecting film is called blooming as shown in figure The refracting index of coating (n_(1)) is less than that of the glass (n_(2)) . 4. If a light of wavelength lambda is incident normally and the thickness of film is t, then optical path difference between waves reflected from upper and lower surface of the film is

If refractive index of MgF_(2) is 1.25, then minimum thickness of film required is (Take lambda = 500 nm )

    Statement-1: When light reflects from the air-glass plate interface, the reflected wave suffers a phase change of pi . Statement-2: The centre of the interference pattern is dark

    A 600 nm light is perpendicularly incident on a soap film suspended air. The film is 1.00 mu m thick with n = 1.35 . Which statement most accurately describes the interference of light reflected by the two surfaces of the film?

    Assertion : In reflection from a denser medium, any ray of light suffers a phase difference of pi . Reason : Denser medium is that medium in which speed of wave is less.

    Statement-1: When a transverse wave is reflected from a denser medium, the trough is reflected as crest and vice-versa. Statement-2: in case of reflection from a denser medium, there is inversion of the reflected wave.
