Dispersion meaning physics
WebOct 14, 2024 · Anomalous Dispersion. When the real index of refraction decreases with increasing wavelength (i.e., d n ∕ d λ < 0, or d n ∕ d ω > 0) the associated dispersion is called “normal” dispersion. This is the situation for water or glass at visible wavelengths. According to Snell’s law, red light will deviate less than blue when passing ...

WebLinear dispersion. Linear dispersion refers to the variation of the refractive index associated with the real part of the χ(1) term, namely, [4] and leads to a wavelength-dependent group velocity which is responsible for pulse broadening and break-up in optical systems.
