A ray of light is travelling from glass to air. (Refractive
index of glass = 1.5). The angle of incidence is 50°.
The deviation of the ray is
(a) 0° (b) 80°
(c) 50° sin⁻¹ [sin 50°/1.5]
(d) sin⁻¹ [sin 50°/1.5] - 50°

Answer:a
μ
g
=1.5
∴1.5=cosecC
Or, C=42
0
.
Critical angle for glass =42
0
. Hence a ray of light incident at 50
0
in glass medium undergoes total internal reflection. δ denotes the deviation of the ray.
δ=180
