Angle of reflection

The angle of reflection measures the angle at which light rebounds from a surface after being reflected.

  • 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, so at a right angle to (900), the boundary between two media.
  • The angle of reflection can be used to understand how light will behave when it interacts with different types of surfaces and objects.
