Across
  1. 3. the change in the direction of a wavefront at the interface between two different media
  2. 5. the spreading of waves around obstacles.
  3. 8. the distance between identical points
  4. 9. the distance a wave travels in a given amount of time
  5. 10. the change in direction of a wave passing from one medium to another caused by its change in speed.
  6. 12. a substance or material that carries the wave.
  7. 13. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
  8. 14. radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.
  9. 15. entire range of wavelengths or frequencies of electromagnetic radiation extending from gamma rays to the longest radio waves and including visible light.
Down
  1. 1. type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction.
  2. 2. apparent difference between the frequency at which sound or light waves leave a source
  3. 4. two waves of identical wavelength are in phase
  4. 6. a wave vibrating at right angles to the direction of its propagation.
  5. 7. the number of waves that pass a fixed point in a given amount of time
  6. 11. waves where the particle motion is in the same direction in which the wave is propagating.
