Question

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

Answer 1

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 material C.

Explanation:

C has the most refractive index i.e., 1.71 among the four materials.  

From the snell’s law, the ratio of the sine of the angles of incidence to the sine of the angles of refraction must be constant for any two given medium.

i.e., n1 sin θ1 = n2 sin θ2

Here, n1= refractive index of medium 1

An n2=refractive index of medium 2,

Θ1= angle of incidence, and

Θ2 = angle of refraction

Now, for this case, the refractive index of material C is maximum resulting in maximum refraction.
