Interference occurs when waves overlap and their resultant displacement is the sum of the displacement of each wave. This result is based on the principle of superposition and the resultant waves may be smaller or larger than either of the two individual waves. Interference of two waves can either be: In phase, causing ...

WebJun 24, 2016 · The word coherent is used to describe the superposition states that you create with coherent fields. Usually you don't have to quantize the field, but can still work in what is know as "semi-classical" approximation. This means that you have aclassical field and a quantized system. This is the more common experimental situation that one … WebThe coherence time, usually designated τ, is calculated by dividing the coherence length by the phase velocity of light in a medium; approximately given by. where λ is the central wavelength of the source, Δν and Δλ is the spectral width of the source in units of frequency and wavelength respectively, and c is the speed of light in vacuum.
WebCoherent sources are formed when two waves have a constant relative phase or a zero or constant phase difference and the same frequency. The features of the interrelationship between physical quantities of a single wave or between numerous waves are described by coherence. Coherence also allows for stationary interference in waves.
