Define absolute refractive index of a medium.Find its value for glass in which speed of light is 2?10 m/s. PLZ REPLY FAST

Dear Student,

Please find below the solution of your asked queries:

Definition- The absolute refractive index of any medium is the refractive index of the medium with respect to vacuum. It is always greater than 1.

Calculation of Absolute refractive index of glass-

For solving this numerical I am assuming that speed of light in glass is 2 * 108 m/sec as the speed given by you seems to be incorrect.

n (absolute refractive index)=c (speed of light in vacuum)speed of light in glass n=3×1082×108n=32n=1.5

Hope this information clears your doubts about the topic.

Keep asking!!
