A ray of light is incident normally on one of the faces of a prism of apex angle 30° and refractive index 
. The angle of deviation of the ray is
Text Solution
Verified by ExpertsThe correct answer is:
C
15°
Using Snell's law for the refraction at AC, we get
r = 45°
Angle of deviation = 45° - 30° = 15°.
