What are the factors that determine the deviation of a ray of light by a triangular prism?
A light ray striking at one face of a triangular glass prism gets refracted twice and emerges out from the other face as shown above. The angle between the emergent and the incident rays is called the angle of deviation. [ [ [ The angle between the two refracting faces involved is called the refracting angle of the prism. ] ]
