Laws of Reflection of Light
Laws of Reflection of Light
The laws that govern how light behaves when it bounces off a surface.
Angle of Incidence vs. Angle of Reflection
Angle of Incidence vs. Angle of Reflection
The angle at which light strikes a surface equals the angle at which it reflects off the surface.
Incident ray, Reflected ray and the normal
Incident ray, Reflected ray and the normal
