Question

state the law of refraction of light.explain the term absolute refractive index of medium and write an expression to relate it with the speed of light in vaccum ?​

Answer 1

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 2

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
