Vedclass · Answer

(C) In Fraunhofer diffraction, the source of light and the screen are effectively at an infinite distance from the aperture (slit).This implies that the wavefronts incident on the slit are plane wavefronts, which means the incident beam must be parallel.This condition is practically achieved by placing the light source at the focus of a converging lens, or by placing the source at an infinite distance from the slit.Therefore, the correct condition is that the source is at infinity and the incident beam is parallel.
