Question

If the refractive index of the medium is high, will the bending be more or less?

Answer 1

According to the Snell's Law of Refraction (sin i )/ (sin r) = refractive index of second medium with respect to the first. Here, 'i' is the angle of incidence of light in the first medium while 'r' refers to the angle of refraction of the light in the second medium.

Hence, the greater the refractive index of the medium in which light is traveling, the greater will be its bending. The refractive index is a measure of the 'optical density' of the medium. The more 'optically denser' the medium, to a greater extent it alters the light's angle.

Answer 2

Refractive Index is the number which tells how much light is bent or refracted while entering a medium. Higher the refractive index lower is the bent or refraction and lower the refractive index higher the bent or refraction.
Snell's Law has proven this by
Refractive Index=sin i/sin r
Where i is angle of incidence in the first medium and r is angle of refraction into the second medium.
