Across
  1. 2. in physics, the time that it takes a complete cycle or wave oscillation to occur
  2. 3. a wave that requires a medium through which to travel
  3. 5. the highest point of a wave
  4. 8. the combination of two or more waves that results in a single wave
  5. 9. a physical envirnment in which phenomena
  6. 12. the number of cycles or vibrations per unit of time; also the number of waves produced in a given amount of time
  7. 13. a wave in which the particles of the medium vibrate parallel to the direction of wave motion
  8. 14. a pattern of vibration that simulates a wave that is standing still
  9. 16. a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
  10. 17. a wave that consists of ascillating electric and magnetic fields, which radiate outward at the speed of light
Down
  1. 1. an observed change in the frequency of a wave when the source or observer is moving
  2. 4. a superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves
  3. 6. the bending of a wave as the wave front passes between two substances in which the speed of the wave differs
  4. 7. a superposition of two or more waves that produces an intensity equal to the difference of the intensities of the individual waves
  5. 10. the lowest point of a wave
  6. 11. the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
  7. 15. a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening
