Wave motion, propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and
De Broglie wave, any aspect of the behavior or properties of a material object that varies in time or space in conformity with the mathematical equations that describe waves. De Broglie waves play an appreciable role only in the realm of subatomic partic
Physics, a branch of science, is the study of forces and their impacts on the environment. Modern physics connects ideas together about the laws of symmetry and conservation (energy, momentum, charge, and parity).See the fact file below for more information on the Physics or alternatively, ...
You might not realize it, but you are surrounded by waves every day! There are several different kinds of waves. In this lesson, you'll learn about mechanical waves and find out what they do. What Are Mechanical Waves? What happens when a raindrop falls into a pool of water? You can...

Although the physics of magnets are pretty well-understood (except perhaps by some hip-hop musicians), and they've been part of our lives for centuries, they do surprise and delight. Here's a look at some fascinating facts about magnets. 1. Magnets come in four flavors: Ferromagnets — wh...

Optical Physics Facts Optical Physics Facts Optical Physics Facts The energy of light is measured in waves on the electromagnetic spectrum. Invisible lights like ultraviolet and X-rays have shorter wavelengths than visible light. A refractive index indicates how much light will slow down traveling ...
Sound waves need a medium to travel through. Since there is no atmosphere in the vacuum of space, the realm between stars will always be eerily silent. That said, worlds with atmospheres and air pressure do allow sound to travel, hence why there's plenty of noise on Earthand likely other...
Tsunamis are sometimes called ‘tidal waves’ but their strength has nothing to do with the tides because their origins are different. About four out of five tsunamis occur within the Pacific Ring Of Fire, a circular zone in the Pacific Ocean where earthquakes and volcanic eruptions frequently ...
