1. What condition is needed for Fraunhofer diffraction? a. The slit must be narrow enough that a substantial amount of diffraction can occur, but not so narrow that it acts as a single point source of waves. b. The light source must be monochromatic. c. The light source must be far enough from the slit that the rays reaching the slit are approximately parallel. d. All of the above.

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.
