Light Interactions: Exploring Reflection Absorption and Refraction Principles

In this video, Mr. Lara introduces the principles of light and its interactions with materials. The session includes a hands-on experiment where a flashlight is used to observe how light reflects, absorbs, or refracts when it encounters different objects. The video provides a recap of these interactions and poses tasks to predict light behavior. It also explores real-world applications of these principles, such as in material design and energy efficiency. The session concludes with encouragement to continue exploring science and learning.
