Worksheet (2 pages) and Homework (1 page) (with answers) for an introduction to reflection, refraction and diffraction of waves.
A corresponding presentation is free to use and embedded at physics.mrhatchard.co.uk in Section 4 (Waves).
Includes definitions, wavefront diagrams, explanations for refraction. Written for the Cambridge IGCSE Coordinated Sciences and Combined Sciences courses, but obviously a large content overlap with various GCSE courses also.
It's good to leave some feedback.
