TED-Ed: What is color? - Colm Kelleher

The video tutorial explains the concept of waves using a cork on water as an example, introducing the idea of periodic motion. It then delves into the measurement of wave period and frequency, illustrating how these concepts apply to light. The tutorial explains that color is the frequency of light waves that our eyes detect, forming the visible spectrum. It concludes by discussing how objects reflect and absorb different colors of light, affecting their appearance.
