- diagrammatically derive and apply the formula for deviation, ,
- graphically demonstrate and use the formula for minimum deviation incidence angle, ,
- use the thin prism approximation formula, .
Prerequisites
Students should already be familiar with
- Snell’s law.
Exclusions
Students will not cover
- dispersion.
