प्रश्न
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

उत्तर
material C
Explanation:
The refraction in a material depends on its refractive index. Refractive index is calculated by ` sin i/sin r`
This ratio is maximum for material C; therefore, it produces maximum refraction.
