What is the meaning of absolute refractive index |
| Answer» Absolute refractive index is the refractive index when a light ray passes from air to the given medium or from a medium to air. We thus apply Snell\'s law as follows(for a ray going from air to a medium), {tex}\\mu{/tex}asini = {tex}\\mu{/tex}msinr. where {tex}\\mu{/tex}m is the refractive index of the medium. | |
