PHY 2054 Lecture Notes - Lecture 24: Lc Circuit, Electric Field, Energy Density
Document Summary
The magnitudes of the electric and magnetic fields of the wave are _____________, and the electric and magnetic energies carried by the wave are _____________. proportional (but not equal) to each other, equal. [ the magnitudes of the electric and magnetic fields of the wave are proportional to each other, according to e = cb. The wave carries equal amounts of electric and magnetic energy. ] The drawing shows an x, y, z coordinate system. A circular loop of wire lies in the z, x plane and, when used with an lc tuned circuit, detects an electromagnetic wave. The wave travels along the z axis, and its electric field oscillates along the x axis. An electromagnetic wave is traveling in a vacuum. The electric field e of the wave is doubled. B doubles, u increases by a factor of four, s increases by a factor of four.
