In the Young’s double slit experiment with sodium light. The slits are 0.589 m a part. The angular separation of the third maximum from the central maximum will be (given λ = 589 nm)

(1) ${\mathrm{sin}}^{-1}\left(0.33×{10}^{8}\right)$

(2) ${\mathrm{sin}}^{-1}\left(0.33×{10}^{-6}\right)$

(3) ${\mathrm{sin}}^{-1}\left(3×{10}^{-8}\right)$

(4) ${\mathrm{sin}}^{-1}\left(3×{10}^{-6}\right)$
