In Young's double-slit experiment the angular width of a fringe formed on a distant screen is `1^(@)`. The wavelength of light used is `6000 Å`. What is the spacing between the slits?

A

`6xx10^(-7)m`

B

`6.8xx10^(-5)m`

C

`3.4xx10^(-5)m`

D

`3.4xx10^(-4)m`

Text Solution

Verified by Experts

The correct Answer is:
C
`theta("in radian")=lambda/d`
`:. d=lambda/theta=(6xx10^(-7))/(pi//180)=3.4xx10^(-5)m`
