  1. 3. The change in direction of a wave passing from one medium to another caused by its change in speed.
  2. 4. The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
  3. 6. A mechanical disturbance from a state of equilibrium that propagates through an elastic material medium.
  4. 8. A wave that is an oscillation of matter, and therefore transfers energy through a medium.
  5. 10. A wave vibrating at right angles to the direction of its propagation.
  6. 12. A wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
  7. 13. The spreading of waves around obstacles.
  8. 16. A substance that makes possible the transfer of energy from one location to another, especially through waves.

  1. 1. The change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.
  2. 2. Vibration generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface.
  3. 5. The change in frequency or wavelength of a wave for an observer who is moving relative to the wave source.
  4. 7. Distance between corresponding points of two consecutive waves.
  5. 9. The flow of energy at the universal speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves, visible light, and gamma rays.
  6. 11. The process in which two or more light, sound, or electromagnetic waves of the same frequency combine to reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves.
  7. 14. The number of crests of a wave that move past a given point in a given unit of time.
  8. 15. Electromagnetic radiation that can be detected by the human eye.
