Ultrashort wave
An arbitrary designation of radio waves of a wavelength of less than 1 m.
-
Shock wave
A compression wave produced by a shock such as an earthquake or explosion that is characterized by a sudden change in air pressure, density, and velocity.
-
Pulse wave
The pressure wave originated by the systolic discharge of blood into the aorta. It is not due to the passage of the ejected blood but is the result of the impact being transmitted through the arterial walls. The velocity in the aorta may be as high as 500 cm/sec and as low as 0.07 cm/sec…

Light wave
An electromagnetic wave that stimulates the retina or other optical sensors.
-
Excitation wave
The wave of irritability originating in the sinoatrial node that sweeps over the conducting tissue of the heart and induces contraction of the atria and ventricles.
-
Electromagnetic wave
A wave-form produced by simultaneous oscillation of electric and magnetic fields perpendicular to each other. The direction of propagation of the wave is perpendicular to the oscillations. The following waves, in order of increasing frequency and decreasing wavelength, are electromagnetic: radio, television, microwave, infrared, visible light, ultraviolet, x-rays, and gamma rays. Waveforms characterized by alternating…
-
Blast wave
A shock wave produced by a blast or explosion. The wave front consists of air under very high pressure that can cause great damage to people, objects, and structures.
-
Afterpotential wave
The wave produced after the action potential wave passes along a nerve. On the recording of the electrical activity, it will be either a negative or positive wave smaller than the main spike.
-
Wave
A disturbance, usually orderly and predictable, observed as a moving ridge with a definable frequency and amplitude.
-
Wattage
The electrical energy produced or consumed by an electrical device, expressed in watts.
