HD Animation: Law of reflection

The animation shows the geometric relationships between the angle of incidence and the angle of reflection of a reflected beam of light. You can move the spotlight interactively with the mouse. You can change the shape of the medium or mirror using the gray circles.

Note on use

After starting the application, you can view the animation in full-screen mode. To do this, click on “View” and then on “Full screen”:

To exit full screen mode, press the Esc key.

Description of the animation

The following elements of the animation can be changed:

  • Position of the spotlight
  • Target point of the spotlight
  • Shape of the surface

Depending on the angle of incidence, the light beam is reflected differently (true to the law “angle of incidence equals angle of reflection”).
