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

O is the angle of prism.

Angle of incidence is the angle made by the incident ray with the normal to the surface of the prism. Here, X represents the angle of incidence.

Angle of emergence is the angle made by the emerging ray with the normal to the surface of the prism. Here, M represents the angle of emergence.

Angle of deviation is the angle made by the emerging ray with the incident ray. Here, Z represents the angle of deviation.

Hence, the correct option is C.
