The property of light travelling in a straight lines in a homogenous transparent medium is known asrectilinear propagation of light
a number indicating the speed of light in a given medium as either the ratio of the speed of light in a vacuum to that in the given medium (absolute index ofrefraction) or the ratio of the speed of light in a specified medium to that in the given medium (relative index ofrefraction) Symbol: n.
