Problem

In Young's double-slit experiment with sodium light, the slits are 0.589 m0.589\,\text{m} apart. The angular separation of the third maximum from the central maximum is, given λ=589 nm\lambda=589\,\text{nm}, (1) sin⁡−1(0.33×10−8)\sin^{-1}(0.33\times10^{-8}) (2) sin⁡−1(0.33×10−6)\sin^{-1}(0.33\times10^{-6}) (3) sin⁡−1(3×10−8)\sin^{-1}(3\times10^{-8}) (4) sin⁡−1(3×10−6)\sin^{-1}(3\times10^{-6})
