Across
- 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.
Down
- 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.
