  1. 4. periodic function of one-dimensional space that moves with constant speed. Consequently, it is a special type of spatiotemporal oscillation that is a periodic function of both space and time
  2. 5. the distance along the direction of propagation between two atoms which oscillate in phase.
  3. 6. an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
  4. 8. position the moment at which the forward reaction of the equilibrium is equal to the backward reaction
  5. 10. wave waves in which the vibration of the medium is parallel ("along") to the direction the wave travels and displacement of the medium is in the same (or opposite) direction of the wave propagation
  6. 11. the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.
  7. 15. A region where the coils are spread apart, thus maximizing the distance between coils
  8. 16. Wavelength is the distance from one point on a wave to the same point on the next wave
  9. 17. the maximum amount of displacement of a particle on the medium from its rest position.
  10. 18. The wavelength in free space of electromagnetic radiation having a frequency equal to a natural resonance frequency of a cavity resonator.
  11. 20. he path length travelled by light in a given time
Down
  1. 1. The refractive index can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values
  2. 2. the distance from one crest to another, or from one trough to another, of a wave
  3. 3. a relative unit of measurement equal to one tenth of a bel (B)
  4. 7. a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave.
  5. 9. Frequency is the number of waves that pass through a point in a second.
  6. 10. the natural agent that stimulates sight and makes things visible.
  7. 12. The horizontal distance between two adjacent crests or troughs
  8. 13. is the application of balanced inward forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions.
  9. 14. the speed at which a wave travels
  10. 19. The horizontal distance between two adjacent crests or troughs
