The angle of reflection measures the angle at which reflected light bounces off a surface.
About the angle of reflection
- The angle of reflection is measured between a ray of light which has been reflected off a surface and an imaginary line called the normal.
- In optics, the normal is a line drawn on a ray diagram perpendicular to (at 900 to), the boundary between two media.
- If the boundary between two media is curved then the normal is drawn perpendicular to the boundary.
