Question
The presence of a nonlinear form of this phenomenon motivates the use of the BBM equation instead of the Korteweg–De Vries (“CORE-teh-veg deh-VREES”) equation, which describes this phenomenon with its “third spatial derivative” term. Solitons and deep water waves respectively exhibit “amplitude” and “frequency” forms of this phenomenon. The angular frequency is written as a function of the wavenumber in this phenomenon’s namesake (*) “relations.” This phenomenon blurs high-contrast areas in a chromatic aberration. Due to this phenomenon, phase velocity varies with frequency, so different wavelengths of light have different indices of refraction. For 10 points, name this phenomenon that causes prisms to create rainbows. ■END■
ANSWER: dispersion [accept word forms describing dispersive systems; accept nonlinear dispersion or amplitude dispersion or frequency dispersion or optical dispersion; prompt on chromatic aberration until “aberration” is read by asking “what phenomenon causes chromatic aberration?”]
