Light and Materials: Exploring Refraction Reflection Absorption and Transmission

Kristen Riley-Panaag introduces the topic of light interaction with materials, focusing on optics. The video covers key concepts such as refraction, reflection, absorption, and transmission of light. Refraction is explained as the bending of light, while reflection is the bouncing back of light. Absorption involves taking in light without reflection, and transmission is the passage of light through materials. The video also distinguishes between transparent, translucent, and opaque materials. A recap of these concepts concludes the tutorial.
