In Young's double slit experiment the two slits are illuminated with light of wavelength `lambda` .The thickness of a film of refractive index `1.4` to be introduced in the path of one of the interfering beams so that the central image shifts by one fringe width is

A double slit experiment is performed with light of wavelength 500nm . A thin film of thickness 2mum and refractive index 1.5 is introduced in the path of the upper beam. The location of the central maximum will

In Young's double slit experiment, the fringes are displaced by a distance x when a glass plate of one refractive index 1.5 is introduced in the path of one of the beams. When this plate in replaced by another plate of the same thickness, the shift of fringes is (3/2)x. The refractive index of the second plate is

In a Young’s double slit experiment, the source illuminating the slits is changed from blue to violet. The width of the fringes

In Young's double slit experiment, using monochromatic light, the fringe patternn shifts by a certain distance on the screen, when a transparent sheet of thickness 't' and refractive index mu is introduced in the path of one of the interfering waves. the sheet is then removed and the distance between the screen and the slits is doubled. it is found that the distance between the successive maxima (or minima) now is the samme as the observed fringe shift when the sheet was introduced. what is the wavelength of light used?

In a Young's double slit experiment using monochromatic light, the fringe pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 and thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the slits and screen is doubled. It is found that the distance between successive maxima now is the same as observed fringe shift upon the introduced of the mica sheet . Calculate the wavelength of the monochromatic light used in the experiment .

In young,s double slit experience monochromatic light, the frings pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 and thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then sheet is then removed and the distance between the slits and the screen is doubled. It is found that now the distance between succesive maximum (or minimum) is the same as the observed fringe-shift upon the introduction o fthe mica sheet. Calculate the wavelength of the monochromatic light used in the experiment.

In Young's double slit experiment the fringe width is 4mm .If the experiment is shifted to water of refractive index 4/3 the fringe width becomes (in mm)
