Define the term absolute refractive index of a medium. 1
(b) Absolute refractive indices of water and glass are 3
4
and
2
3
respectively.
(i) In which one of the two media is the speed of light more ?
(ii) If a ray of light enters obliquely from glass to water, will it
bend towards the normal or away from the normal ? 1
(c) The absolute refractive indices of water and glass are 3
4
and
2
3
respectively. If the speed of light in glass is 2 108 m/s, find the
speed of light in (i) water and (ii) vacuum.
