The MATLAB toolbox is available here. Four simple vector equations (or one tensor equation and an asssociated dual) describe the unified electromagnetic field and more or less directly imply the theory of relativity. 3 (noting in particular Equation 1. Although he contributed a huge amount of work to physics, he died in 1879 at the age of 48. Often, equations are conjectured like conjurors pulling tricks out of a hat to match experimental observations.

It looks more complicated but in reality it’s easy to use (you may need a calculator), and it works the same way as the previous charts. Since the field is equal to the (negative) potential gradient we can say that the potential difference (V) between two points separated by a distance l and the magnitude of the average electrostatic field are related thus: E = V l. The power carried by the wave is derived. We often characterize the energy carried by a wave in terms of its intensity, which is the power per unit area.
