Light, radiant heat (infrared radiation), X rays, and radio waves are all examples of traveling electromagnetic waves. Electroma
gnetic waves comprise combinations of electric and magnetic fields that are mutually compatible in the sense that the changes in one generate the other.The simplest form of a traveling electromagnetic wave is a plane wave. For a wave traveling in the x direction whose electric field is in the y direction, the electric and magnetic fields are given byE =E0sin(kxt)j^,B =B0sin(kxt)k^.This wave is linearly polarized in the y direction.In these formulas, it is useful to understand which variables are parameters that specify the nature of the wave. The variables E0 and B0 are the __________ of the electric and magnetic fields.(A) maxima(B) amplitudes(C) wavelengths(D) velocities
The equations of the electric and magnetic fields given are sinusoidal functions. he sine function varies between the value of -1 and 1 when is multiplied by a number A then varies from -A to A. In this case the variation goes from -E0 to E for the electric field and from -B0 to B0 for the magnetic field. Because the amplitude is half of the distance between the highest and the lowest value of the sinusoidal function. In the electric field is: E0-(-E0)/2=E0 and in the magnetic field B0-(-B0)/2=B0.
Yes there is an elastic collision in physics its when a collision occurs but no kinetic energy is loss. We study them in order to understand how to conserve momentum.
