Question

write the definition of refractive index from snell's law​

Answer 1

Answer:

Snell's law tells us the degree of refraction and relation between the angle of incidence, the angle of refraction andrefractive indices of a given pair of media. We know that light experiences the refraction or bending when it travels from one medium to another medium. Snell's law predicts the degree of the bend.

plz mark me brainlist

Answer 2

Answer:

Ratio of sine angle of incidence and sine angle of refraction is constant it can also be said refractive index. Other absolute refractive index =speed of light in vaccum/speed of light in medium
