Angle of reflection

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.
