Visible light of wavelength \(6000 \times 10^{-1} \mathrm{~cm}\) falls normally on a single slit and produces a diffraction pattern. It is found that the second diffraction minimum is at 60° from the central maximum. If the first minimum is produced at θ1, then θ1 is close to:
- 20°
- 45°
- 30°
- 25°
Answer
(A) 20°
