refractionrelated
Refractionrelated is a term used to describe phenomena, effects, and studies associated with refraction, the change in direction of a wave as it passes at an interface between media with different propagation speeds. In the context of optics, refraction is governed by Snell's law: n1 sin theta1 = n2 sin theta2, with n representing the refractive index of each medium. Refraction can affect light, sound, and other waves, and may be accompanied by dispersion when phase velocity depends on wavelength.
Common manifestations include the apparent bending of light from objects submerged in water, optical lenses shaping
Measurement and characterization rely on refractive index data, refractometry, and spectroscopic methods. The index depends on
