Across
  1. 4. What is the source of all waves
  2. 6. The number of to-and-fro vibrations in a given time
  3. 8. Vibration is in the direction of travel
  4. 10. Is described in terms of frequency, speed, amplitude, and wavelength
  5. 11. Is a change in frequency as measured by an observer due to the motion of the source or listener
  6. 14. The combined effect of two or more overlapping waves.
  7. 15. The time it takes for a complete vibration
Down
  1. 1. When light is incident on a rough surface it is reflected in many directions
  2. 2. is the propagation of a disturbance through a medium
  3. 3. Bending of light by means other than reflection and refraction
  4. 5. Vibration is at right angles (sideways) to wave travel
  5. 7. What refract when parts of the wave fronts travel at different speeds
  6. 9. Describes how fast the disturbance moves though the medium
  7. 12. The bending of a wave due to a change in the medium and/or speed of the wave
  8. 13. Occurs whenever successive impulses are applied to a vibrating object in rhythm with its natural frequency
