(1.10) Note that setting this equal to zero, we get the equation of an outgoing sphere of light as seen by either observer. (Don’t forget that if c 6= 1, then t becomes ct.) Maxwell formulated four equations for free space, which are mentioned below: 1. First Maxwell’s Equation: Gauss’s Law for Electricity. Gauss's law of electricity states that “the electric flux passing through a closed surface is equal to 1/ε0 times the net electric charge enclosed by that closed surface”.
