An EM wave is also a transverse wave. EM waves have an electric and a magnetic component that are both perpendicular to the direction of wave propagation. Unlike many other types of waves, EM waves require no matter to be present for propagation. EM waves move at the speed of light and ...

The ratio of the speed of light in a vacuum to that in a medium is the 'index of refraction, n.' Just a few months ago, a team at the Ecole Politechnique Lausanne alleged that they had produced the first photograph of light particles and waves! I am not sure that I understood ...
The amplitude of a wave is the distance between its highest point and the point of equilibrium. This highest point is called the antinode. In most waves, the antinode appears to move along the length of the medium. With a standing wave, the antinode remains in the same place, because the...
Transverse waves A mechanical wave is transverse when all the particles of the medium, which are solid or liquid (and never gas), vibrate perpendicularly at right angles, up and down, and continue to move in the direction of the wave. For example, the ripples on the surface of a lake ar...
