In the Young's experiment with sodium light, the slits are o .589 mm apart. what is the angular width of the fourth maximum ? Given that $\lambda$. = 589 nm

• A

  ${\sin }^{-1}\left(4\times {10}^{-3}\right)$

• B

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

• C

  ${\sin }^{-1}\left(0\cdot 33\times {10}^{-6}\right)$

• D

  ${\sin }^{-1}\left(0\cdot 33\times {10}^{-8}\right)$
