Exploring Light, Color, and Rainbows

The video explores the nature of light, explaining it as a form of energy that travels in waves. It introduces the electromagnetic spectrum, which includes visible and invisible light, such as radio waves and gamma rays. The video discusses how light's wavelength relates to its energy, with longer wavelengths having less energy. It explains how prisms and rainbows reveal the colors in white light, and how colors are perceived based on the light reflected by objects. The video concludes by emphasizing the importance of light in seeing colors.
