Across
  1. 3. The distance between two identical points on consecutive waves (crest to crest or trough to trough)
  2. 5. The maximum displacement of a wave from its resting position (wave height)
  3. 9. How fast a wave travels depends upon the medium, calculated by multiplying frequency × wavelength
  4. 10. A repeating disturbance that transfers energy through a medium or space
  5. 11. The time it takes for one full cycle of a wave to pass a point
  6. 12. The full range of electromagnetic waves, from radio waves to gamma rays
  7. 13. Information we gather to support or refute a scientific claim
Down
  1. 1. A form of electromagnetic energy that carries information about the universe
  2. 2. A type of wave where the disturbance is perpendicular to the direction of travel
  3. 4. A wave made of oscillating electric and magnetic fields that can travel through space
  4. 6. A type of wave where the disturbance is parallel to the direction of travel
  5. 7. The number of wave cycles that pass a point in one second
  6. 8. A wave that requires a medium (like air, water, or a rope) to travel through=Earthquakes
