A monochromatic beam of light is used for the formation of fringes on a screen by illuminating the two slits in the Young,s double slit interference experiment. When a thin film of mic is interposed in the path of one of the interfering beams

A thin sheet of a transparent material (mu= 1.60) is placed in the path of one of the interfering beams in a YDSE using sodium light, lambda= 5890 dotA . The central fringe shifts to a position originally occupied by the 12th bright fringe. Calculate the thickness of the sheet.

A glass sheet 12xx10^(-3) mm thick (mu_(g)=1.5) is placed in the path of one of the interfering beams in a Yongs's double slit interference arrangement using monochromatic light of wavelenght 6000 A. If the central bright fringe shifts a distance equal to width of 10 bands. What is the thickness of the sheet of diamond of refractive index 2.5 that has to be introduced in the path of second beam to bring th ecentral bright fringe to original position?

When a mica sheet of thickness 7 microns and mu=1.6 is placed in the path of one of interfering beams in the biprism expriment then the central fringe gets at the position of seventh bright fringe. What is the wavelength of light used?

In the ideal double-slit experiment, when a glass-plate (refractive index 1.5) of thickness t is introduced in the path of one of the interfering beams (wavelength lambda ), the intensity at the position where the central maximum occurred previously remains unchanged. The minimum thickness of the glass-plate is

In the ideal double-slit experiment, when a glass-plate (refractive index 1.5) of thickness t is introduced in the path of one of the interfering beams (wavelength lambda ), the intensity at the position where the central maximum occurred previously remains unchanged. The minimum thickness of the glass-plate is

In a YDSE, fringes are produced by monochromatic light of wavelength 5450Å. A thin plate of glass of refractive index 1.5 is placed normally in the path of one of the intefering beams and the central bright band of the fringe system is found to move into the position previoysly occupied by the third band from the centre. select the correct alternatie
