Revise AQA GCSE Physics 6.2.2 Properties of electromagnetic waves 1 with the question bank, lessons, revision guides, and flashcards.
(HT only) Different substances may absorb, transmit, refract or reflect electromagnetic waves in ways that vary with wavelength. • (HT only) Some effects, for example refraction, are due to the difference in velocity of the waves in different substances. • (HT only) Students should be able to use wave front diagrams to explain refraction in terms of the change of speed that happens when a wave travels from one medium to a different medium.
