Angle of Deviation in a Glass Triangular Prism Experiment

[Chirag Gupta]

In an experiment to trace the path of a ray of light through triangular glass prism.
Can the angle of deviation be zero? Why?

What do you think?
The answer for a rectangular prism would be yes.

PS: I assume that we can discount shining the beam down the length of the prism.

Not a rectangular prism , a triangular prism with angle of prism = 60degrees .

Yes I know you asked about a triangular prism. My reference to a rectangular prism was a hint.
