Solution
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, Mrepresents 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.
