Question

Write some terms related to the prism.

Answer 1

Prism:

A polyhedron in which two faces are in a parallel plane and the other is a parallelogram.

Related terms:

1. The angle of deviation ($\angle \mathrm{ẟ}$): The angle of deviation is the angle between the incident ray and the emergent ray.
2. Incident angle ($\angle \mathrm{i}$): The angle of the incidence is the angle made by the incident ray with the normal to the surface.
3. Emergent Angle ($\angle \mathrm{e}$): The emergent angle is the angle of the rays leaving the medium with the normal surface at the exit point.
4. Prism angle ($\angle \mathrm{A}$): The angle between the two faces of a prism is called the prism angle.
5. Refraction angle ($\angle \mathrm{r}$): The angle between the refracted ray and the normal drawn at the point of incidence on the interface where refraction occurs.
