In a version of Young’s double slit experiment, the slits are separated by a distance of
1.0 mm. The light from the slits is observed on a screen that is 12 m from the slits. If the
wavelength of the light is 550 nm, what is the linear distance on the screen between the
first order (m = 1) and second order (m = 2) dark fringes?
The Attempt at a Solution
y = Ltanθ = 12tan0.04727
y = Ltanθ = 12tan0.07878°
