When different waves collide (e.g. sound from different sources) they interfere with each other. This is called, unsurprisingly, wave interference.PhasingThe following table illustrates how sound waves (or any other waves) interfere with each other depending on their phase relationship:...
Natural materials all have a positive refractive index, and this dictates how light waves interact with them. Refractivity stems in part from chemical composition, but internal structure plays an even more important role. If we alter the structure of a material on a small enough scale, we can ...

A prominent signature of plasma — a state of matter characterized by freely roaming charged particles interacting via electromagnetic forces — is the generation of “plasma waves,” resulting from an instability of plasma distributions. “Fast magnetosonic waves” (MSWs) are one kind of ele...
Sound Waves Air, like all matter, consists of molecules. Even a tiny region of air contains vast numbers of air molecules. The molecules are in constant motion, traveling randomly and at great speed. They constantly collide with and rebound from one another and strike and rebound from objects...
Unless you are sitting right beside the transmitter, your radio receiverneeds an antennato help it pick the transmitter's radio waves out of the air. An AM antenna is simply a wire or a metal stick that increases the amount of metal the transmitter's waves can interact with. ...
If you made the antenna longer it would receive better, but AM stations are so strong in cities that it doesn't really matter if your antenna is the optimal length. You might wonder why, when a radio transmitter transmits something, radio waves want to propagate through space away from ...
Machine-to-Machine (M2M) communication has been a thing for quite some time, perhaps starting with the telemetric systems of the early 20th century that transmitted encoded readings from measuring instrumentation over phone lines, radio waves or satellite communications. The first was used in 1912 ...
These waves move through matter, such as air, water or the ground. They interact with the matter (and, in some cases, with each other) as they go. The animation below will show you the basics of sound waves and how they travel. Sound waves can pass through one another without much ...
