Q. The main difference between the phenomena of interference and diffraction is that
A) Diffraction is caused by reflected waves from a source whereas interference is caused due to refraction of waves from a source
B) Diffraction is due to interaction of waves derived from the same source, whereas interference is that bending of light from the same wavefront
C) Diffraction is due to interaction of light from wavefront, whereas the interference is the interaction of two waves derived from the same source
D) Diffraction is due to interaction of light from the same wavefront whereas interference is the interaction of waves from two isolated sources
Explanation
(c) In interference, we use two sources while in diffraction, we use light from two points of the same wavefront.
