A light wave is incident normally over a slit of width

24 \times {10^{ - 5}}\;cm

. The angular position of second dark fringe from the central maxima is

30^\circ

. What is the wavelength of light

View answer and explanation

Correct option: A

6000\mathop \mathrm{A}\limits^ \circ

Option A (

6000\mathop \mathrm{A}\limits^ \circ

) is correct because it is the wavelength calculated using the formula for the angular position of the second dark fringe in single-slit diffraction.
