Across
  1. 4. what we see when no colors or light enter our eye
  2. 5. a quick back-and-forth movement
  3. 7. the type of visible light we see when all colors enter our eye at the same time
  4. 9. the rate (how often) something that repeats over and over
  5. 10. a substance or material (solid, liquid, gas)
  6. 11. how loud a sound is, which depends on the amplitude of its sound wave
  7. 13. the type of wave in which the movement of the wave's medium is perpendicular (up and down) to the direction the wave is moving
  8. 14. describes when an object takes in or soaks up certain waves of light
  9. 16. the high point of a wave
  10. 17. a high frequency/energy form of electromagnetic radiation that can be used to see through human skin and take pictures of bones
  11. 19. another name for a compression wave
  12. 21. when a wave changes direction or speed as it enters a new medium
  13. 22. the height of the peak/crest of a wave above the resting line
  14. 24. the name for any type of wave that can only travel through a medium (solid, liquid, gas)
  15. 26. the type of wave in which a wave's medium is compressed (squeezed) in the same direction as the movement of the wave
  16. 28. the length of one wave, can be measured as the distance from the center of one peak (crest) to the center of the next peak (crest)
  17. 29. the low point of a wave
  18. 30. the name for a particle of light or packet of light
Down
  1. 1. the of electromagnetic radiation with the highest energy and frequency, and shortest wavelength
  2. 2. the type of energy in movement/motion
  3. 3. a back and forth pattern of motion that transfers energy
  4. 6. when a wave bounces off an object
  5. 8. 2words a mathematical relationship where if one variable increases, the other decreases (example: frequency vs wavelength)
  6. 12. the name for any wave created by an earthquake
  7. 15. the type of light we can see
  8. 18. the type of light with a frequency just above what humans can see, but can cause sunburns and skin damage
  9. 20. the type of electromagnetic wave with the lowest energy and frequency, and the longest wavelength
  10. 23. the reflection of sound off a distant surface
  11. 25. the ability to do work
  12. 27. the highness or lowness of a sound, which depends on the frequency of its sound wave
