Rossby Waves

Science / Weather / Rossby Waves: The movement of ridges and troughs in the upper wind patterns, primarily the jet stream, circling the earth. Named for Carl-Gustaf Rossby, a U.S. Weather Bureau (NWS) employee, who first theorized about the existence of the jet stream in 1939.

Radio Waves

Technology / Cell Phones / Radio Waves: Electromagnetic energy with frequencies in the 3000 hertz (3 kHz) to 300 billion Hertz (300 GHz) portion of the electromagnetic spectrum. MORE

Sound Waves

Technology / Home Audio / Sound Waves: Fluctuating waves of barometric pressure that travel through a physical medium such as air. An acoustic wave consists of a traveling vibration of alternate compressions and rarefactions, whereby sound MORE

Primary Seismic Waves

Science / Geology / Primary Seismic Waves: The fastest set of earthquake vibrations - also known as P-waves. They move through the Earth in compression and expansion motions (much like sound waves move through air). Called primary because they MORE

Microwaves

Technology / Cell Phones / Microwaves: A subset of radio waves that have frequencies ranging from around 300 million waves per second (300 MHz) to three billion waves per second (3 GHz). MORE

Light Waves

Science / Weather / Light Waves: That part of the electromagnetic spectrum that contains visible light. The colors, from longest wave length to shortest, are red, orange, yellow, green, blue, indigo, and violet (ROY G. BIV). MORE
