الصوت والضوء: قانون انعكاس الضوء

The video tutorial explains the concept of light reflection, focusing on how light rays bounce off shiny surfaces like mirrors. It introduces the terms 'incident ray' and 'reflected ray' and describes how to measure angles of reflection using a normal line. The tutorial covers the two laws of reflection: the first law states that the angle of incidence equals the angle of reflection, while the second law asserts that the incident ray, reflected ray, and the normal line all lie in the same plane.
