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 refracted when they arrive at a boundary between one material and another.

Please note that the core practical activity on the refraction of light is also covered in this video.
