Young's double slit Experiment
Question

In the Young's double slit experiment with sodium light, the slits are 0.589 m apart. The angular separation of the third maximum from the central maximum will be (given λ=589 mm)

Moderate
Solution

Using relation, dsinθ=sinθ=d

For n = 3, sinθ=3λd=3×589×1090.589

=3×106 or θ=sin13×106
