Interference is the phenomenon where two or more light waves superimpose to form a resultant wave of greater, lower, or the same amplitude. This can affect the visibility and clarity of microscopic images.

Interference can be constructive or destructive depending on the phase relationship between the interacting waves.
Constructive interference occurs when waves are in phase, resulting in increased amplitude and brightness.
Destructive interference occurs when waves are out of phase, leading to decreased amplitude and dimmer or dark areas.
Interference patterns are crucial for techniques like differential interference contrast (DIC) microscopy, which enhances image contrast by exploiting differences in optical path length.
The wavelength and coherence of light sources influence the pattern and extent of interference.
