In this episode you will learn: - How to apply the wave equation (v = fλ) to solve for speed, frequency, or wavelength. - The critical difference between mechanical waves like sound, which need a medium, and electromagnetic waves like light, which do not. - A mnemonic to memorize the order of the electromagnetic spectrum from lowest to highest frequency. - The core principles of reflection (bouncing) and refraction (bending) and how they are tested conceptually on the AFOQT. - Common exam traps, such as confusing the inverse relationship between frequency and wavelength or mixing up reflection and refraction.
