Question

Discuss the diffraction of light due to single thin slit

Answer 1

Diffraction from a single slit. Young's experiment with finite slits: Physclips - Light. Phasor sum to obtain intensity as a function of angle. Aperture. Physics with animations and video film clips. Physclips provides Light bends around obstacles like waves do, and it is this bending which causes the single slit diffraction pattern. Some assumptions must be made for this description of the single slit diffraction pattern: The slit size is small, relative to the wavelength of light. The screen is far away.

Answer 2

• The diffraction pattern arises due to interference of light waves from different symmetrical point of the same wavefront.

• The diffraction pattern due to a single slit consists of a central bright band having alternate dark and weak bright bands of decreasing intensity on both sides.
