Fig.  (a) A triangular glass prism and (b) its principal section


The two plane faces ABED and ACFD inclined to each other are called refracting faces of the prism.

The line AD along which the two refracting faces meet is called refracting edge of the prism.
The face BCFE opposite to the refracting edge is called base of the prism.
The angle A at which the two refracting faces are inclined to each other is called Angle of the prism.

A section ABC made by a plane, at right angle to the refracting edge is called principal section of the prism.
