A two slit Young's interference is done with monochromatic light of wavelength 6000Å. The slites ar e2mm apart and fringes are observed on a screen placed 10cm away fromm the slits and it is found that the interference pattern shifts by 5mm, when a transparent plate of thickness 0.5mm is introduced in the path of one of slits. What is the refractive index of the transparent plate?

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 double slit experiment is done with monochromatic light of wavelength 6000 Å . Slits are 2 mm apart and fringes are observed on a screen placed 10 cm away from the slits. If a transparent plate of thickness 0.5 mm is placed in front of one of the slit, interference pattern shifts by 5 mm. Then refractive index of transparent plate should be :

YDSE is conducted using light of wavelength 6000 Å to observe an interference pattern. The slits are 2mm apart. The fringes are observed on a screen 10cm away from the slits. When a film of some material 0.5mm thick was placed over one of the slits, the fringe pattern shifted by a 5mm . What is the refractive index of the material of the film ?

Two slits, 4 mm apart, are illuminated by light of wavelength 6000 Å . What will be the fringe width on a screen placed 2 m from the slits

Two slits, 4 mm apart, are illuminated by light of wavelength 6000 Å . What will be the fringe width on a screen placed 2 m from the slits

In Young's double slit experiment the slits apart by 3 mm are illuminated with a source of monochromatic light of wavelength 6000 Å. Interference fringes are obtained on a screen at a distance of 1 m from the slits . The width of the fringe will be

A Lloyd's mirror or length 5 cm is illuminated with monochromatic light of wavelength lambda (= 6000 Å) from a narrow 1 mm slit in its plane and 5 cm plane from its near edge. Find the fringe width on a screen 120 cm from the slit and width of interference pattern on the screen.
