6.6.2.2 Properties of electromagnetic waves 1
| Content | Key opportunities for skills development |
|---|---|
(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. Students should be able to construct ray diagrams to illustrate the refraction of a wave at the boundary between two different media. | |
(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. | WS 1.2 |
Required practical activity 21: investigate how the amount of infrared radiation absorbed or radiated by a surface depends on the nature of that surface.
AT skills covered by this practical activity: physics AT 1 and 4.
This practical activity also provides opportunities to develop WS and MS. Details of all skills are given in Key opportunities for skills development (page 191).
