2) How does diffraction differ from interference?
Ans: Diffraction is the bending of waves around an obstacle, while interference is the superposition of two waves. In interference, waves emitted from two coherent sources get superposed while; in diffraction the waves emitted from different points of a limited part of the same wave front get superposed.
