1.	State the laws of refraction of light. Explain the term „absolute refractive index of a medium‟and write an expression to relate it with the speed of light in vacuum
Answer» Laws of refraction STATE that: The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell's law of refraction The term 'absolute REFRACTIVE index' of a medium is defined as the ratio of the velocity of light in a vacuum to the velocity of light in the medium refractive index= SPEED of light in air / speed of light in the given medium HOPE it has helped you

Laws of refraction STATE that: The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell's law of refraction

The term 'absolute REFRACTIVE index' of a medium is defined as the ratio of the velocity of light in a vacuum to the velocity of light in the medium

refractive index= SPEED of light in air / speed of light in the given medium
