In a Young's d ouble slit experiment, a monochromatic light of wavelenght 600 nm is used. If the two slits are covered bt transparent sheets of thickness 0.132 mm and 0.1 mm of refractive index 1.5, then the number of fringes that will shift due to introdiction of the sheets are

In double-slit experiment using light of wavelength 600 nm, the angular width of a fring formed on a distant screen is 0.1^(@) . What is the spacing between the two slits ?

Interference fringes are obtained in a Young's double slit experiment using beam of light consisting two wavelengths 500 nm and 600 nm. Bright fringes due to both wavelengths coincide at 2.5 mm from the central maximum. If the separation between the slits is 3 mm, then the distance between the screen and plane of the slits is
