Answer:
the above expression is for absolute refractive index ⬆️⬆️⬆️
refraction of light occurs according to the following laws
- the incident Ray the refracted Ray and the normal to the interference of two transparent media at the point of incidence all lie in the same plane
- the ratio of sine of angle of incidence to the Sine of angle of refraction for the light of given colour is constant for a given pair of media
Explanation:
the extent of the change in direction that takes place in the given pair of media is expressed in terms of refractive index
the refractive index of a medium with respect to vacuum is called absolute refractive index of the medium

Answer:
HERE IS UR ANSWER.
Refractive index of a medium = Speed of light in vacuum/Speed of light in a medium
1.5 = 3 x 108 / Speed of light in medium
Speed of light in the medium = 3 x 108 /1.5
= 2 x 108 m/s
