Correct Answer: Option C
Explanation:

where A = the refracting angle of the prism(60o)
D = angle of deviation of the ray (30o)
= 1/√2/1/[sub]2[/sub]√2/2/1/[sub]2[/sub]
= √2/2 x 2/1 = √2
n = √2
| sin(A/2) |
where A = the refracting angle of the prism(60o)
D = angle of deviation of the ray (30o)
| sin(60/2) |
| sin 30 |
= 1/√2/1/[sub]2[/sub]√2/2/1/[sub]2[/sub]
= √2/2 x 2/1 = √2
n = √2
