In a diffraction pattern due to a single slit of width $$a$$, the first minimum is observed at an angle 30^o when light of wavelength 5000 $$\mathop A\limits^ \circ $$ is incident on the slit. The first secondary maximum is observed at an angle of

sin^$$-$$1$$\left( {{1 \over 2}} \right)$$

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

$${\sin ^{ - 1}}\left( {{1 \over 4}} \right)$$

$${\sin ^{ - 1}}\left( {{2 \over 3}} \right)$$
