Exploring Light Energy: Reflection, Transmission, and Absorption

The video tutorial explains the nature of light as a form of energy, its travel in straight lines, and how it can be reflected, transmitted, or absorbed. It introduces the visible spectrum, highlighting that black is an absence of light. The tutorial also covers how light interacts with different materials, such as transparent glass and colored objects, affecting how we perceive colors.
