A ray of light from a denser medium strikes a rarer medium at an angle of incidence i as shown in the figure. The reflected and refracted rays make an angle of
90 ∘
with each other. The angles of reflection and refraction are r and r'. The critical angle is
A s i n − 1 ( t a n r ) B s i n − 1 ( t a n i ) C s i n − 1 ( t a n r ′ ) D t a n − 1 ( t a n i ) Open in App Solution
The correct option is A
s i n − 1 ( t a n r )
From figure, i = r and r' =
90 ∘ − r Now, n = s i n r ′ s i n r = s i n ( 90 ∘ − r ) s i n r ⇒ n = c o s r s i n r = 1 t a n r We know that, n = 1 s i n C
where C = critical angle
∴ 1 s i n C = 1 t a n r ⇒ C = s i n − 1 ( t a n r ) Suggest Corrections 18
