Light Behavior and Optics Concepts

The video explores the concepts of reflection and refraction, demonstrating how light behaves when it encounters different surfaces and materials. It explains the wave nature of light, the role of lenses in focusing light, and the use of optical fibers in communication. The video also covers the greenhouse effect, illustrating how light and heat interact with glass structures.
