Q. A beam of light wavelength

Q. In a Young's double slit experiment, the distance between the slits & the screen is

100 cm .

For a certain distance between the slits, an interference pattern is observed on the screen with the fringe width

0.25 mm

. When the distance between the slits is increased by

1.2 mm,

the fringe width decreased to

2 / 3

of the original value. In the final position, a thin glass plate of refractive index

is kept in front of one of the slits & the shift of central maximum is observed to be

20

times the initial fringe width. Find the thickness of the plate.

Q. In Lloyd's mirror experiment, a light wave emitted directly by the source

S (narrow slit)

interferes with the wave reflected from a mirror

M

. As a result, an interference fringe pattern is formed on the screen which is

1 m

far from mirror. The source and the mirror are separated by a distance

l = 100 cm

. At a certain position of the source, the fringe width on the screen was equal to

β = 0.25 mm

and after the source was moved away from the mirror plane by

Δ h = 0.60 mm

the fringe width decreased by

1.5 times

. Find the wavelength of light from the source.
