A parallel beam of monochromatic light of wavelength 460 nm passes through a long slit of width 0.1 mm. What is the angular divergence in which most of the light is diffracted? |
$2.3 × 10^{-3} rad$ $4.6 × 10^{-3} rad$ $9.2 × 10^{-3} rad$ $9.2 × 10^{-6} rad$ |
$9.2 × 10^{-3} rad$ |
The correct answer is Option (3) → $9.2 × 10^{-3} rad$ |
