Hi

Interference:

Interference is due to waves emerging from two different sources, producing different wavefronts.

It occurs due to the superposition of the light waves from two sources.

The direction of the wave propagation direction does not change after the superposition. The Fri

Diffraction

Diffraction is spreading out of waves when they pass through an aperture.

Diffraction, is due to the secondary waves that emerge from the different parts of the same wave.

It occurs due to the superposition of the secondary wavelengths.

The direction of the wave propagation direction changes after diffraction.
