Exploring Light Waves: Chapter 1 Lesson 1.2

The video tutorial introduces students to the concept of light waves and how they interact with materials. Dr. Desiree Whitmore, a spectroscopist, shares insights into her work and demonstrates various experiments in the lab, including using lasers and cameras to study light. The video encourages students to think critically about light and its applications, inviting them to reflect and ask questions.
