Question

the amount that a light ray bends when it enters a new medium depends on what?

Answer 1

a) amount absorbed by the medium
b)speed of light in the medium
c)speed of light in vaccum
d)amount of water in the medium...
which one?

Answer 2

anyone know? i really need an answer, or at least a link of some sort! please and thank you :)

Answer 3

speed of light in medium

Answer 4

The bending is dependant on the difference in the refractive index of the two mediums and the angle of incidence.
If the light is traveling along the normal, there is no refraction.
If the light passes from a medium with a high refractive index into a medium with a low refractive index, the light bends away from the normal.
If the light is at the critical angle from the normal, it will refract to travel along the interface. If the light is incident at an angle greater than the critical angle it will reflect from the interface rather than refract.

Answer 5

All those statements are true.
