Across
  1. 3. you see a distorted view of someones body in a pool as the light bends as it travels
  2. 7. region in a longitudinal (sound) wave where the particles are farthest apart
  3. 9. the time taken to complete one oscillation
  4. 10. a skateboarder coasting downhill has
  5. 12. a pancake cooking on a frying pan
  6. 16. when you can hear a friend from another room as the sound waves bend around the corner of a wall
  7. 17. the lowest point in a wave cycle
  8. 19. waves where the disturbance moves perpendicular to the direction of the wave
  9. 20. oil, coal, and gasoline are all examples of this type of nonrenewable energy
  10. 21. region in a longitudinal (sound) wave where the particles are closest together
  11. 23. when the suns rays travel through empty space to
  12. 25. a plate hanging over the edge of a table has
  13. 27. are waves that can travel through a vacuum (empty space)
  14. 29. the highest point in a wave cycle
Down
  1. 1. when a wave strikes an object or surface and bounces off
  2. 2. this type of heat transfer occurs when your feet make direct contact with hot sand at the beach
  3. 4. the height of a wave. This can be measured from the resting position (middle) of the wave to the crest or to the trough
  4. 5. number of wave crests per second
  5. 6. waves where the disturbance moves in the same direction as the wave
  6. 8. solar, wind, and hydroelectric are all examples of this type of energy
  7. 11. waves that require a medium. These waves travel when molecules in the medium collide with each other passing on energy
  8. 13. this law states that energy can’t be created or destroyed, only converted from one form of energy to another
  9. 14. this type of heat transfer occurs when an AC unit circulates air throughout a house
  10. 15. when waves combine and form a new wave when as they overlap
  11. 18. examples include plastic, rubber, and wood
  12. 22. the distance from one wave crest to the next or one compression to the next
  13. 24. how fast the disturbance of the wave is moving. This is measured by multiplying the frequency by the wavelength
  14. 26. a traveling disturbance that moves through space and matter
  15. 28. reflected sound
