Q. Illustrate what is the dissimilarity between diffraction and interference?
Answer:-
Diffraction is the yielding of waves around an obstacle while interference is the meeting of two waves. For illustration diffraction is what results from a pinhole blocking a wave source the wave spreads out from that one point. This outcome is what creates shadows regions where the light source is blocked but it is not completely dark. Interference nevertheless results from two waves colliding with one another undergoing constructive as well as destructive interference as in two chords being played. I think the mystification concerning these two different phenomena is the truth that two pinholes two diffraction sources results in interference of two sources which is what the diffraction grating is which creates the characteristic bands of light and dark interference patterns.
