The refractive indices of four materials $A,\ B,\ C$ and $D$ are $1.33,\ 1.43,\ 1.71$ and $1.52$ respectively. When the light rays pass from air into these materials, they refract the maximum in:(a) material A (b) material B (c) material C (d) material D
(c) material C
Explanation:
The refraction or the amount of bending of light depends on the refractive index (μ) of the two media. It is calculated by $\frac {sin\ i}{sin\ r}$.
Thus, when the light rays pass from air into these materials, the refraction will be maximum for material C as it has the maximum refractive index i.e 1.71. And, due to this, the speed of light gets slower in this medium.
