... Initially unpolarized light of intensity I0 is sent into a system of three polarizers as shown. What fraction of the initial intensity emerges from the system? What is the polarization of the exiting light? • Through the first polarizer: unpolarized to polarized, so I1=½I0. • Into the second polariz ...

... gravitational potential. It is the potential energy between any two charges. • Energy is a force times a distance, so if you multiply the Electric Force times a distance (I am oversimplifying a little here) you get the Electric Potential. • U = k q1 q2 / r (and is in units of Joules) • Note how simi ...
