Seismic Surface Wave

Science / Geology / Seismic Surface Wave: A seismic wave that follows the earth's surface only, with a speed less than that of S-waves. There are Raleigh waves (forward and vertical vibrations) and Love waves (transverse vibrations). 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

Forced Wave

Science / Tides and Currents / Forced Wave: A wave generated and maintained by a continuous force. MORE

Gravity Wave

Science / Tides and Currents / Gravity Wave: A wave for which the restoring force is gravity. MORE

Refraction (Wave)

Science / Geology / Refraction (Wave): The departure of a wave from its original direction of travel at the interface with a material of different index of refraction (light) or seismic wave velocity (see also Seismic refraction). MORE
