5.Use google to search about the definition of refractive indexThe speed of light in the vacuum The spped of the ligt in the medium The ratio of the speed of light in a vacuum to its speed in a specific medium

When light travels from air to an optically denser medium, its speed is decreased by 25%. What is the refractive index of the medium? A 0.75 B 1.00 C 1.16 D 1.33

A ray of light travels with a speed of 2 ×× 10810 8 in a medium `A' and enters into another medium `B' travelling with velocity 2.5 ×× 10810 8 m/s. If absolute refractive index of medium `A' is 1.52. Calculate the refractive index of medium `B' with respect to `A'.(Find answer upto one places of decimal)0.50.20.81

The expression for refractive index is given bySelect one:a.  N = v/cb.  N = c/vc. N = 1/cvd. N = cv
