In a biprism experiement, by using light of wavelength `5000Å`, `5mm` wide fringes are obtained on a screen `1.0m` away from the coherent sources. The separation between the two coherent sources is

A

1 mm

B

`0.1 mm`

C

`0.05 mm`

D

`0.01 mm`

Text Solution

Verified by Experts

The correct Answer is:
B
`d=(D)/(beta) lambda=(1xx5xx10^(-7))/(5xx10^(-3))=0.1 mm`
