In doubIe sIit experiment using Iight of waveIegth 600 nm , the anguIar width of a fringe formed on a distant screen is `0.1^(@)` .What is the spacing between the two sIits ?

Text Solution

Verified by Experts

Using d sin `theta =n lambda` we get
`d= (n lambda)/(sin theta)= (1xx 600 xx 10^(-9))/(sin theta )=3.43 xx 10^(-4)` m
