A flake of glass (refractive index 1.5) is placed over one of the opening of a double-slit apparatus. The interference pattern displaced itself through seven successive maxima toward the side where the flake is placed. If wavelength of the light is `lambda = 600 nm`, then the thickness of the flake is

A flake of glass (refractive index 1.5) is placed over one of the openings of a double slit apparatus. The interference pattern displaces itself through seven succesive maxima towards the side where the flake is placed. If wavelength of the diffracted light is lambda=600nm , then the thickness of

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?

If a thin mica sheet of thickness 't' and refractive index mu is placed in the path of one of the waves producing interference , then the whole interference pattern shifts towards the side of the sheet by a distance

If a thin mica sheet of thickness 't' and refractive index mu is placed in the path of one of the waves producing interference , then the whole interference pattern shifts towards the side of the sheet by a distance

In a Young's double-slit experiment,a thin sheet of mica is placed over one of the two slits.As a result,the center of the fringe pattern (on the screen) shifts by an amount corresponding to 30 dark bands. The wavelength of the light in this experiment is 480 nm and the refractive index of the mica is 1.60 .The mica thickness is (approximately):

Determine what happens to the double slits interference pattern if one of the slits is covered with a thin, transparent film whose thickness is lambda/(2(mu-1)) , where lambda is the wavelength of the incident light and mu is the index of refraction of the film.

Determine what happens to the double slits interference pattern if one of the slits is covered with a thin, transparent film whose thickness is lambda/(2(mu-1)) , where lambda is the wavelength of the incident light and mu is the index of refraction of the film.

What is the minimum thickness of thin film required for constructive interference in the reflected light through it ? (Given, the refractive index of the film =1.5, wavelength of the lilght incident on the film =600 nm.
