In a Young's double slit experiment, light of 500 nm is used to produce an interference pattern. When the distance between the slits is 0.05 mm, the angular width (in degree) of the fringes formed on the distance screen is close to:

A

`0.17^(@)`

B

`0.57^(@)`

C

`1.7^(@)`

D

`0.07^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`beta _(0) = (lambda)/(d) = (500 xx 10 ^(-9))/( 5 xx 10^(-5)) = 10^(-2) ` Radian `= 0.57^(@)`
