Consider a case of thin film interference as shown.Thickness of film is equal to wavelength of light in `mu_(2)`

Reflected light will be maxima if `mu_(1)lt mu_(2)lt mu_(3)`

Reflected light will be maxima if `mu_(1)lt mu_(2)gt mu_(3)`

Transmitted light will be maxima if`mu_(1)gt mu_(2)gt mu_(3)`

Transmitted light will be maxima if `mu_(1)gt mu_(2)lt mu_(3)`

When a transparent film of refractive index 1.5 is kept over one of the openings of a double slit experiment apparatus, the interference pattern is shifted through six successive maxima, towards the side, where the film was placed. What is the thickness of the film if the wavelength of light used in 6000 Å?

4200 nm

5200 nm

7200 nm

6200 nm

dispersion of light

interference of light

absorption of light

scattering of light

may be of any magnitude

should be much smaller than `lamda`

should be of the order of `lamda`

should be a few thousand times of `lamda`
