quantum mechanics, especially that version originally developed (1926) by the Austrian physicist Erwin Schrodinger. See Schrodinger equation.
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 the motion ...
wave number
a unit of frequency in atomic, molecular, and nuclear spectroscopy equal to the true frequency divided by the speed of light and thus equal to the number of waves in a unit distance. The frequency, symbolized by the Greek letter ...
wave velocity
distance traversed by a periodic, or cyclic, motion per unit time (in any direction). Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product ...
wave-cut platform
gently sloping rock ledge that extends from the high-tide level at the steep-cliff base to below the low-tide level. It develops as a result of wave abrasion; beaches protect the shore from abrasion and therefore prevent the formation of platforms. ...
wave-particle duality
possession by physical entities (such as light and electrons) of both wavelike and particle-like characteristics. On the basis of experimental evidence, the German physicist Albert Einstein first showed (1905) that light, which had been considered a form of electromagnetic waves, ...
waveguide
any of a class of devices that confines and directs the propagation of electromagnetic waves, such as radio waves, infrared rays, and visible light. Waveguides take many shapes and forms. Typical examples include hollow metallic tubes, coaxial cables, and optical ...
wavelength
distance between corresponding points of two consecutive waves. "Corresponding points" refers to two points or particles in the same phase-i.e., points that have completed identical fractions of their periodic motion. Usually, in transverse waves (waves with points oscillating at right ...

Occurrences include Zbiroh, Czech Republic; Montebras, France; Barnstaple, Devon, ...
wavemeter
device for determining the distance between successive wavefronts of equal phase along an electromagnetic wave. The determination is often made indirectly, by measuring the frequency of the wave. Although electromagnetic wavelengths depend on the propagation media, wavemeters are conventionally calibrated ...
