Light Behavior and Properties

The video tutorial by Teacher Edson covers the behavior, transmission, speed, and intensity of light. It begins with an introduction and attendance check, followed by a discussion on how light behaves, forms shadows, and travels in a straight path. The tutorial then explains how light transmits through transparent, translucent, and opaque materials. The speed of light in different mediums, such as air, water, and glass, is detailed, highlighting how it slows down in denser materials. Finally, the intensity of light is discussed, showing how it diminishes with distance from the source.
