Abstract
In this section of Resonance, we invite readers to pose questions likely to be raised in a
classroom situation. We may suggest strategies for dealing with them, or invite responses,
or both. “Classroom” is equally a forum for raising broader issues and sharing personal
experiences and viewpoints on matters related to teaching and learning science.We know that the condition for minimum deviation
of a ray passing through a prism is that
the angle of incidence is equal to the angle of
emergence. It is generally proved by using differential
calculus. Here two proofs have been
provided without using calculus, the ¯rst by application
of trigonometry only and the second by
pure reasoning.
