A double slit is illuminated with monochromatic light of wavelength 6.11 × 102 nm. The m = 0 and m = 1 bright fringes are separated by 1.8 cm on a screen which is located 3.5 m from the slits. What is the separation between the slits?
Added by Elisa A.
Step 1
We know that the distance between two adjacent bright fringes on a screen is given by the equation: d sinθ = mλ where d is the separation between the slits, θ is the angle between the line connecting the slits and the screen, m is the order of the bright fringe, Show more…
