Question

refraction of light .refractive index

Answer 1

When light moves from a medium of a given refractive index, n1, into a second medium withrefractive index, n2, both reflection andrefraction of the lightmay occur. The Fresnel equations describe what fraction of the light isreflected and what fraction is refracted When light moves from a medium of a given refractive index n1 into a second medium withrefractive index n2 both reflection andrefraction of the lightmay occur.

Answer 2

Answer:

Refraction of light

light changes its direction when going form one transparent medium to another transparent medium. this is called the refraction of light.

Refractive index

Refractive index depends in the velocity of light in the medium.
