Wave motion is the motion in which the particle/matter remains at the point where it is. But the disturbance/energy gets transfer from one point to the other. The particle just oscillates about its mean position. But it does not travel.
Show that average value of Poynting vector for a plane e-m wave is 1/2 √μ/e XH 2 .
Laue pattern (M. von Laue): The pattern generated on a photographic film while high-frequency electromagnetic waves (such as x-rays) are fired at a crystalline solid.
