WebStudents must first understand two terms: coherent and incoherent light. Light emitted by normal means such as a flashlight or a bulb, is incoherent or the photons of the many wave frequencies of light are oscillating in different directions. It is not a stream of light. Coherent light is a beam of photons (almost like particles of light waves ... WebMay 6, 2024 · You are right that light from a filament is incoherent. It is temporally incoherent (multi-wavelength) and spatially incoherent (spread out in space). A slit does increase the spatial coherence of the light: if you consider the slit to be a source, it can be much smaller than the filament.

WebCoherence describes the properties of the interrelation between physical quantities of a single wave or between several waves. Two waves are coherent when they have a constant relative phase or when they have zero or constant phase difference and the same frequency. Coherence is also the property which enables waves to have stationary interference.
