Recall and apply the formula 1/n = sin c, which relates the critical angle to the refractive index.

Quick explanation

Recall and apply the formula 1/n = sin c, which relates the critical angle to the refractive index

• This point belongs to Refraction of light, especially Refraction of light outcomes.
• You need to be able to recall and apply the formula 1/n = sin c, which relates the critical angle to the refractive index.
• The key ideas to know are Recall and Use.
• Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
