Answer to Question #21033 in Optics for vinesh

Question

write difference between interfernce and diffraction of light?

Answer 1

Interference is a phenomenon inwhich two or more waves superimpose. Diffraction is rather a phenomenon that's connected with a single wave encountering an obstacle. To establish a relation between the two concepts, diffraction is often described as interference of multiple virtual secondary waves that are formed from a single wave in this contact with an obstacle.
