In the experiment to trace the path of a ray of light through a triangular prism,
1. A student is asked to draw the boundary of the prism , why?

2. If the angle of incidence is 30, what can be the measure of the angle of incidence at minimum deviation ?

1. It ensures that prism is always kept within this boundary during the experiment.

2. At the minimum deviation condition,

The angle of emergence= angle of incidence
