Opaque vs. Transparent

The video tutorial explains how light helps us see by illuminating objects. It describes different sources of light, such as the sun, electricity, and fire. The tutorial differentiates between light rays and beams, and discusses how opaque objects block light while transparent objects allow it to pass through. Examples of opaque and transparent objects are provided, including curtains, glass, and water. The interaction of sunlight with opaque objects like tree branches is also explored, demonstrating how sunbeams are created. The video encourages viewers to experiment with light using a flashlight to understand these concepts better.
