Lesson: Deviation due to a Prism Physics

Start Practising

In this lesson, we will learn how to determine the effect of the shape and refractive index of a prism on the path taken through it by light rays.

Lesson Plan

Students will be able to

  • diagrammatically derive and apply the formula for deviation, 𝛼=𝜙+𝜃−𝐴,
  • graphically demonstrate and use the formula for minimum deviation incidence angle, 𝜙=(𝛼+𝐴)2,
  • use the thin prism approximation formula, 𝑛=(𝛼+𝐴)𝐴.
