Question

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

Answer 1

(a)$\huge\mathcal\orange{</h2><h2>3/2}$

Refractive Index of B with respect to A

=$\large\bf\pink{sin i/sin r}$

=sin60/sin45

= ( √3 /2) /(1/ √2)

= √6/2

=1.225
