Physics MCQs

Which of the following options is NOT a correct difference between the interference and diffraction?

Interference is because of the superposition of secondary wavelets from two different wavefronts that are produced by two coherent sources, while diffraction is because of the superposition of secondary wavelets that are emitted from different points of the same wavefront.

In Interference, fringes are equally spaced, while in diffraction, fringes are unequally spaced.

In Interference, bright fringes are of the same intensity, while in diffraction, the intensity of the fringes falls rapidly.

Interference has lesser number of fringes as compared to the diffraction.
