In this neat video from 1940, by the Handy Organization, the science of light is introduced. It’s an educational video, which explains and demonstrates the most important facts about light that were known back in those days. In particular, the infra-red and ultra-violet light is introduced. Also, the main physical properties of light are shown through the demonstrations of diffraction and reflection. Interestingly, the video is concluded by introducing the new headlights of Chevrolet, which, as explained in the video, employed many of the mentioned scientific breakthroughs. This is because the Handy Organization was funded by General Motors to make such educational videos to promote their cars.
