Light Reflection and Parallax Concepts

Anne Rank introduces geometrical optics, explaining light as a form of energy. She discusses how light travels in straight lines and the types of reflection: specular and diffuse. The laws of reflection are covered, including the concepts of incident and reflected rays, and the formation of virtual and real images. The video concludes with an explanation of parallax, its effects, and its application in the gaming industry.
