Two slits `4.0 xx 10^(-6)` m apart are illuminated by light of wavelength 600nm . What is the highest order fringe in the interference pattern?

Text Solution

Verified by Experts

`Deltax = dsintheta =nlambda`
n= (dsintheta)/(lambda)`
`n_max = d/lambda = (4.0 xx 10^-6)/(600 xx 10^-9)`
= 6.66
Highest integer is 6.
