Electromagnetic Waves

A parallel plate capacitor with plate area $A$ and separation between plates $d$ is charged with constant current $I$. Consider a plane surface of area $\frac{5 A}{6}$ parallel to the plates and drawn between the plates. The displacement cu...

The electric and the magnetic field associated with an E.M. wave, propagating along the \(\mathrm{Z}\)-axis can be represented by

An electromagnetic wave is propagating along X-axis. At x = 1 cm and t = 18s, its electric vector |E| = 8 V/m, then the magnitude of its magnetic vector is
