Electromagnetic Spectrum | UNC-TV Science
Illuminate lightwaves, even those not visible to the human eye, in a concise activity about the electromagnetic spectrum. Pupils watch and listen to an animated video describing the electromagnetic spectrum as well as frequency and...
Curated OER
The Science of Light
We really only see objects that emit light, either on their own or by reflecting light from another source. Past misconceptions of light are illustrated, and current understandings of light illuminated. This could be used as an...
