This video tutorial explores the fundamental properties of light, including its propagation, reflection, refraction, and dispersion. It explains how light travels in straight lines, how it can be reflected by surfaces, and how it passes through transparent and opaque materials. The tutorial also covers the concepts of refraction and dispersion, illustrating how light bends when passing through different media and how it can be split into a spectrum of colors. Additionally, the formation of shadows is discussed, highlighting the interaction between light and objects.
