Worksheet (2 pages) and Homework (1 page) (with answers) for Refractive Index. Including questions on the concept and definition, and calculations to find the refractive index, the angle of incidence, and the angle of refraction.
A corresponding presentation is free to use and embedded at physics.mrhatchard.co.uk in Section 4 (Waves).
Written for the Cambridge IGCSE Coordinated Sciences and Combined Sciences courses, but obviously a large content overlap with various GCSE courses also.
