  1. 7. is the net effect of the combination of two or more wave trains moving on intersecting or coincident paths
  2. 13. one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity
  3. 14. wave A wave that oscillates back and forth on an axis
  4. 16. a force that squeezes something together
  5. 17. the transport of energy without the transport of matter
  6. 18. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
  7. 19. a point on a surface wave where the displacement of the medium is at a maximum
Down
  1. 1. wave motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
  2. 2. the spreading of waves around obstacles
  3. 3. when light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence
  4. 4. such as a solid or liquid takes up another substance
  5. 5. segment of one cycle of a longitudinal wave during its travel or motion
  6. 6. the number of waves that pass a fixed point in unit time
  7. 8. A passage or transfer as of a disease from one individual to another or of neural impulses from one neuron to another
  8. 9. A substance that makes possible the transfer of energy from one location to another
  9. 10. is an oscillation of matter
  10. 11. a long depression less steep than a trench
  11. 12. The change in direction of a wave, such as a light or sound wave away from a boundary the wave
  12. 15. the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocity of the ray in the first medium to the velocity in the second medium and the incident ray
