Rays and Optical beams
... In geometrical optics, the propagation of optical waves can be described approximately by using the concept of rays. This is valid provided the beam diameter is much larger than the wavelength and the diffraction can be neglected. The rays travel in straight lines in homogeneous media and obey Ferma ...

JAP04 - Anglictina pro fyziky 4 Refractive index
... Let summarize it all. The refractive index of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical glass has a refractive index of 1.5, which means that light travels at 0.67 times the speed in air or vacuum. Tw ...
