Classical Physics


Faster Than the Brighter-Light Beacon

Authors: S.Baune

We analyse the motion of a spot of light projected onto a flat screen by a rotating source. We find that the motion of the spot has many interesting features such as spot splitting and superluminal effects. Our discussion is well suited for undergraduates and can be an interesting add-on to their curriculum, giving them new insights into the effects of kinematics.
