Light's Journey Explained
Light travels at varying speeds depending on the medium, with denser materials causing it to slow down. When photons encounter a boundary between different substances, they can be reflected, absorbed, or transmitted. Absorption occurs when materials "swallow" photons, often re-emitting them at a lower energy level, altering their frequency and energy in the process. Understanding these interactions is crucial for grasping the nature of light.In this clip
