In a regular YDSE, when thin film of refractive index mu is placed in front of the upper slit then it is observed that the intensity at the central point becomes half of the original intensity. It is also observed that the initial 3^(rd) maxima is now below the central point and the initial 4^(th) minima is above the central point. Now, a film of refractive index mu_(1) and thickness same as the above film. is put in the front of the lower slit also. It is observed that whole fringe pattern shifts by one fringe width. What is the value of mu_(1) ?

Statement-1: In YDSE, if initial phase difference between waves is pi , central maxima will be occupied by minima. Statement-2: In YDSE , if incident light is white light, then central fringe is white while all other fringes are coloured. Statement-3 : A thic transparent liquid film floating upon water, when illuminated by while light, appears coloured.

Interference fringes were produced in Young's double-slit experiment using light of wavelength 5000 Å . When a film of thickness 2.5xx10^(-3) cm was placed in front of one of the slits, the fringe pattern shifted by a distance equal to 20 fringe-widths. The refractive index of the material of the film is

In YDSE when slab of thickness t and refractive index mu is placed in front of one slit then central maxima shifts by one fringe width. Find out t in terms of lambda and mu .

Statement I: In YDSE, if separation between the slits is less than wavelength of light, then no interference pattern can be observed. Statement II: For interference pattern to be observed, light sources have to be coherent.

Statement-1: In Young's double slit experiment the two slits are at distance d apart. Interference pattern is observed on a screen at distance D from the slits. At a poit on the screen when it is directly opposite to one of the slits, a dard fringe is observed then the wavelength of wave is proportional of square of distance of two slits. Statement-2: In Young's double slit experiment, for identical slits, the intensity of a dark fringe is zero.

Statement-1: if white light is used in YDSE, then the central bright fringe will be white. Statement-2: In case of white light used in YDSE all the wavelengths produce their zero order maxima at the same position.

A thin transparent sheet is placed in front of a slit in Young's double slit experiment. The fringe width will
