Question
A ray of light is incident on an equilateral glass prism (μ = √3) and moves parallel to the base of the prism inside it. The angle of incidence for this ray is :-
Options
A.60o
B.45o
C.30o
D.90o
Solution
r1 = 
= 30o
1 × sini = μ × sinr1
sini = √3 sin30o
∴ i = 60o
= 30o1 × sini = μ × sinr1
sini = √3 sin30o
∴ i = 60o
