In a Fraunhofer diffraction experiment at a single slit using
\( \mathrm{P} \) a light of wavelength \( 400 \mathrm{~nm} \), the first minimum is formed at an angle of \( 30^{\circ} \). The direction \( \theta \) of the first secondary maximum is
W given by :
(A) \( \sin ^{-1}\left(\frac{2}{3}\right) \)
(B) \( \sin ^{-1}\left(\frac{3}{4}\right) \)
(C) \( \sin ^{-1}\left(\frac{1}{4}\right) \)
(D) \( \sin ^{-1}\left(\frac{2}{3}\right) \)
