3. the movement of light conceptualized as a wave, defined by such properties as reflection, refraction, and dispersion.
6. the number of cycles or completed alternations per unit time of a wave or oscillation. Symbol : F; Abbreviation : freq.
7. an unusually large sea wave produced by a seaquake or undersea volcanic eruption.
12. a wave in which the direction of displacement is the same as the direction of propagation, as a sound wave.
13. a disturbance on the surface of a liquid body, as the sea or a lake, in the form of a moving ridge or swell.
14. an image; representation; counterpart.
16. the speed at which the phase of a wave is propagated, the product of the frequency times the wavelength. This is the quantity that is determined by methods using interference.
17. the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.

1. a wave in which the direction of displacement is perpendicular to the direction of propagation, as a surface wave of water.
2. a wave that is an oscillation of matter, and therefore transfers energy through a medium.
4. the ratio of the radiant flux transmitted through and emerging from a body to the total flux incident on it: equivalent to one minus the absorptance.
5. the change of direction of a ray of light, sound, heat, or the like, in passing obliquely from one medium into another in which its wave velocity is different.
8. a middle state or condition; mean.
9. the removal of energy or particles from a beam by the medium through which the beam propagates.
10. a longitudinal wave in an elastic medium, especially a wave producing an audible sensation.
11. a wave that propagates as an oscillation of matter, and therefore transfers energy through a medium.
15. the highest part of a hill or mountain range; summit.
