Across
  1. 6. A span of electromagnetic waves, ranging from lowest to highest frequencies(two words
  2. 7. The number of to-and-fro vibrations in a given time
  3. 8. Describes how fast the disturbance moves through the medium(two words)
  4. 10. Vibration is at right angles (sideways) to wave travel
  5. 11. Vibration is in the direction of travel
Down
  1. 1. When light is incident on a rough surface, it is reflected in many directions.
  2. 2. Electromagnetic waves created by vibrating electric charges with frequencies that fall within the range of sight
  3. 3. A wiggle in space and time— a disturbance that travels from one place to another transporting energy.
  4. 4. A wiggle in time
  5. 5. The returning of a wave to the medium through which it came when it encounter a reflective surface
  6. 9. The time it takes for a complete vibration
