The Inverse Square Law The Inverse Square Law
... Because the same power flows through ever-increasing areas, its concentration per same area diminishes inversely with the square of the radius. This result is true not only for electromagnetic waves, but for any mechanical wave produced by a point source. It is the reason why you cannot read a book ...

The Photoelectric Effect
... If the conditions are right, a beam of light can knock electrons out of the surface of a metal. When the effect was first discovered, one of the most striking things about it was that it could not be explained by the classical theory of electromagnetism, the only available theory of light at the tim ...
