1A prism deviates light because the ray refracts at two non-parallel faces.
2The angle of minimum deviation occurs when the light ray enters and exits the prism symmetrically, making the path through the prism shortest. This happens at a specific angle of incidence that depends on the refractive index and geometry of the prism. In exams, always draw accurate ray diagrams to show how light bends as it enters and exits a prism. Use Snell's law to calculate angles accurately and remember to consider the angle of minimum deviation for full marks.
3Refraction Through a Prism should be revised by linking the physical idea, the formula or diagram cue, and the final result.
4Keep the physical observation and the reason separate, then connect them clearly.
