In a YDSE with two identical slits, when the upper slit is covered with a thin, perfectly tranparent sheet of mica, the intensity at the centre of screen reduces ro 75% of the initial value. The second minima is observed to above this point and third maxima below it. which of the following can not be a possible value of phase difference caused by the mica sheet

In YDSE, one of two slits is covered by a transparent paper which transmits only half the ligth intensity. How will the intensity of maxima and minima change ?

In a double slit experiment a parallel beam of light strikes the slit plane at an angle theta as shown in the figure. The two slits are covered with transparent plastic sheets of equal thickness t but of different refractive indices 1.2 and 1.5. The central maxima is formed at the centre of the screen at C. (a) Which sheet was used to cover the slit S1? (b) Find theta .

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 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) ?

The young's double slit experiment is done in a medium of refractive index 4//3 .A light of 600nm wavelength is falling on the slits having 0.45 mm separation .The lower slit S_(2) is covered by a thin glass sheet of thickness 10.4mu m and refractive index 1.5 .the intereference pattern is observed ona screen placed 1.5m from the slits are shown (a) Find the location of the central maximum (bright fringe with zero path difference)on the y-axis. (b) Find the light intensity at point O relative to the maximum fringe intensity. (c )Now,if 600nm light is replaced by white light of range 400 to700 nm find the wavelength of the light that from maxima exactly point O .[All wavelengths in this problem are for the given medium of refractive index 4//3 .Ignore dispersion]
