In a Young’s double slit experiment, the slit separation is `0.2 cm`, the distance between the screen and slit is 1 m . Wavelength of the light used is `5000 Å`. The distance between two consecutive dark fringes (in mm ) is

A

0.25

B

0.26

C

0.27

D

0.28

Text Solution

Verified by Experts

The correct Answer is:
A
`beta= (lambdaD)/(d)` [distance between two consecutive dark fringes]
`implies beta= (5000 xx 10^(-10) xx 1)/(0.2 xx 10^(-2))= 0.25 mm`
