The video tutorial explains the concept of light reflection on smooth surfaces like mirrors. It defines key terms such as incident and reflected rays, point of incidence, and normal. The laws of reflection are discussed, emphasizing that the angle of incidence equals the angle of reflection. An experiment is demonstrated to show how mirrors change the direction of light, confirming that light travels in a straight path and does not bend.
