In biprism experiment the fringe width is `0.30 mm`. If slits are covered by glass plate of thickess `0.04` mm and refractive index `mu=1.5` then the fringe widht is

A

`0.02 mm`

B

`0.1 mm`

C

`0.30 mm`

D

`0.2`mm

Text Solution

Verified by Experts

The correct Answer is:
C
If slits are covered by glas plate only and if there is no change in other parameters of experiments then there is no change in fringe widht.

In Young's double slits experiment, light of wavelength 4000Å is used to produced bright fringes of width 0.6 mm, at a distance of 2m . If the whole apparatus is dipped in a liquid of refractive index 1.5, then the fringe width will be

In Young's double slit experiment, the fringes are displaced by a distance x when a glass plate of one refractive index 1.5 is introduced in the path of one of the beams. When this plate in replaced by another plate of the same thickness, the shift of fringes is (3/2)x. The refractive index of the second plate is

In a double-slit experiment, fringes are produced using light of wavelength 4800A^(@) . One slit is covered by a thin plate of glass of refractive index 1.4 and the other slit by another plate of glass of double thickness and of refractive index 1.7. On doing so, the central bright fringe shifts to a position originally occupied by the fifth bright fringe from the centre. find the thickness of the glass plates.

A plane monochromatic light falls normally on a diaphragm with two narrow slits separated by a distance d = 2.5 mm. A fringe pattern is formed on the screen placed at D = 100 cm behind the diaphragm. If one of the slits is covered by a glass plate of thickness 10mu m , then distance by which these fringes will be shifted will be :
