Step 1
We know that the formula for the double-slit interference pattern is given by dsinθ = mλ, where d is the separation between the slits, θ is the angle to the mth order bright fringe, and λ is the wavelength of the light. Show more…

Light with a wavelength of $520 \mathrm{~nm}$ is used in a two-slit experiment. If the angle to the first bright fringe above the central fringe is $0.067^{\circ}$, what is the separation of the slits?
(I) The third-order fringe of 610 $\mathrm{nm}$ light is observed at an angle of $18^{\circ}$ when the light falls on two narrow slits. How far apart are the slits?
