Difference between interference and differaction frige?

Interference fringes are formed when two or more coherent light waves overlap and produce alternating light and dark bands due to constructive and destructive interference. Diffraction fringes, on the other hand, are formed when light waves encounter an obstruction or aperture, causing them to bend and interfere with each other, resulting in a pattern of alternating light and dark regions. In essence, interference fringes arise from the superposition of multiple light waves, while diffraction fringes result from the bending of light waves around obstacles.
