  • Figure 10.1 shows a ray of light as it travels from medium A to medium B. Refractive index of the medium B relative to medium A is (a) √3 /√ 2 (b) √2 / √3 (c) 1/ √2 (d) 2

Figure 10.1 shows a ray of light as it travels from medium A to medium B. Refractive index of the medium B relative to medium A is

(a) \sqrt{3}/\sqrt{2}

(b) \sqrt{2}/\sqrt{3}

(c) {1}/\sqrt{2}

(d) \sqrt{2}

Answers (1)

Answer : A

Refractive index of B with respect to A =\frac{\sin\; i}{\sin\; r}

=\frac{\sin\; 60^{o}}{\sin\; 45^{o}}

=\frac{\sqrt{3}}{\sqrt{2}}
