Electromagnetic waves 1



Visible light is just one of the types of waves which make up the electromagnetic (EM) spectrum.  In this video, we’ll look at some of the properties which all EM waves have in common, including the fact they can all be reflected and refracted when they arrive at a boundary between one material and another.

The required practical activities on the reflection and refraction of light are also covered in this video.

Please note that this video includes some higher tier-only content.
