I am feeling worried about what topics I should spend time revising for the Level 2 Waves exam. Often Study Guides provide a lot of information but some of it won’t actually be tested in the exam. I want to make sure that I don’t waste time revising things which won’t be in the exam.
In reference to the ESA Study Guide Level 2 Physics (latest version), are the following topics relevant to be tested in the Level 2 Waves Standard?
Dispersion - refraction by prism (anything to do with prisms) (pg 86 - 87)
Images formed in two mirrors and 90 degrees to each other (pg 68)
Diffraction of light (pg 62)
f = r/2 (pg 71)
