Question

The path of a ray of light passing through a glass prism is shown below :
In this diagram the angle of prism, angle of incidence, angle of emergence and angle of deviation respectively have been represented by:

• A. O, Y, Z and N,
• B. P, Y, M and Z,
• C. O, X, M and Z
• D. P, X, Z and N

Answer 1

The correct option is C O, X, M and Z

Angle of prism $=\angle O$ , (angle between two refracting surfaces)

Angle of incidence $=\angle X$ (angle between incident ray and normal) ,

Angle of emergence $=\angle M$ (angle between emergent ray and normal)

Angle of deviation $=\angle Z$ (angle between incident ray and emergent ray)
