In Young’s experiment, monochromatic light through a single slit S is used to illuminate the two slits S_1 and S_2 . Interference fringes are obtained on a screen. The fringe width is found to be w. Now a thin sheet of mica (thickness t and refractive index mu ) is placed near and in front of one of the two slits. Now the fringe width is found to be w’, then :

A two slit Young's interference experiment it done with monochromatic light of wavelength 6000 A . The slits are 2 mm apart. The fringes are observed on a screen placed 10 cm away from the slits. Now a transparent plate of thickness 0.5 mm is placed in front of one of the slits and it if found that the interference pattern shifts by 5 mm . The refractive index of the transparent plate is :

A Young's double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is

In Young's double slit experiment, if the two slits are illuminated with separate sources, no interference pattern is observed because

In Young's double slit experiment , red light of wavelength 620 nm is used and the two slits are 0.3 mm apart . Interference fringes are observed on a screen 1.3 mm apart . Calculate (i) the distance of slits from the screen and (ii) the fringe width if this distance is doubled .

In a Young's double-slit experiment, green light is incident on the two slits. The interference pattern is observed on a screen. Which one of the following changes would cause the observed fringes to be more closely spaced?

In Young's double slit experiment the slits are 0.5 mm apart and interference is observed on a screen placed at a distance of 100 cm from the slits. It is found that the 9^(th) bright fringe is at a distance of 8.835 mm from the second dark fringe from the centre of the fringe pattern. Find the wavelength of light used.
