Question

For the refraction of a ray of light through a glass prism, the path of a ray of light is; Shown below:; The angle of incidence, the angle of emergence and the angle of deviation respectively have been represented by; A. Y, N, Z; B. X, Z, M; C. X, N, Z; D. X, M, Z(All India - 2013)

Answer 1

Explanation:

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, Mrepresents the angle of emergence.

Answer 2

Answer:

Option - D = XMZ

Explanation:

In the following diagram, the angle of incidence is <X, the angle of emergence will be <M and the angle of deviation is denoted by <Z.
