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

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.

A transparent glass plate of thickness 0.5 mm and refractive index 1.5 is placed infront of one of the slits in a double slit experiment. If the wavelength of light used is 6000 A^(@) , the ratio of maximum to minimum intensity in the interference pattern is 25/4. Then the ratio of light intensity transmitted to incident on thin transparent glass plate is
