Q. Light of wavelength $6000 \,A^\circ$ from a distant source falls on a slit 0.5mm wide. The distance between two dark bands on each side of the central bright band of the diffraction pattern observed on a screen placed at a distance 2m from the slit is.

Wave Optics

Solution:

Required distance = $\frac{2D \lambda}{d}$
