Across
  1. 3. -place where longitudinal waves
  2. 4. or Wide spectrum light is important for1. Plant Growth2. Melatonin Production3. Vitamin D production4. Serotonin production
  3. 5. the direction the wave bounces off the object.
  4. 6. waves-waves that travel through Matter (solid, liquid or gas)
  5. 11. waves - .Im (10cm)
  6. 13. filtering out light waves So all you see are waves going I direction
  7. 14. - (near sighted) the image is focused in front of the cornea When things are far away making them blurry
  8. 21. -you cannot see through it at all
  9. 22. change when you focus to thinner near if or relax pull it to make it thicker to focus.
  10. 24. range of sound 20-20,000 Hz
  11. 25. -Reflection of sound waves
  12. 26. waves - waves that vibrate at a right angle to the direction it is traveling.
  13. 28. the nomber of waves passing
  14. 30. light - (all the colors you don't see)
  15. 31. using sound
  16. 33. - when waves go from I medium and the light is bent
  17. 34. lens- a convex lens that focuses light on I point.
  18. 37. primary colors combine to make white (light Shining in multiple Colors) Source colors Red, blue, green
  19. 38. -When waves bounce off an object
  20. 40. unit of measure for intensity of sound.
  21. 42. - the direction the wave. is hitting the object
  22. 44. (remotes) .0001 m
  23. 46. the bottom of the wave :
  24. 47. waves are both vertical & "horizontal yet always perpendicular to the direction it is traveling
  25. 50. waves- vibration is parallel to the direction the wave is traveling
  26. 51. (loudness) - a measure of how loud the sound is. intensity at source and distance from source
Down
  1. 1. - particles in the medium the Wave is going through cause a redirection
  2. 2. visable light each color has its Own wavelength
  3. 7. Waves- Waves that travel through both air and a vacuum 300,000,000 m/s in space
  4. 8. of sound from the source outwards in a straight line in all directions
  5. 9. a change in frequency when the source is moving. (and to a lesser effect if listerer is moving
  6. 10. -completely see through
  7. 12. - (far sighted) the image focus is behind the cornea making anything in arm's length blurry.
  8. 15. light - heat lamps at fast food places
  9. 16. filter Made with very Close lines.
  10. 17. light the colors of light that you see
  11. 18. Sounds with pitch over 20,000 (too high for humans to hear)
  12. 19. - Clear, curved objects designed to bend light.
  13. 20. the angle of reflection equals the angle of incidence
  14. 23. primary colors Colors reflecting back the color you see is reflected all other colors are absorbed Reflected Colors. if all colors present see black yellow cyan & magenta
  15. 27. a measure of the height of crest and trough from the (a a measure of volume)
  16. 29. lens- a concave lense that bends light outwards.
  17. 32. Wave lengths red orange yellow green blue violet
  18. 33. waves- 10,000m (87-1500 radio stations)
  19. 35. a measurement of the pitch of Sound.
  20. 36. Sounds with a pitch Under 20 Hz (too ap low for humans to hear)
  21. 39. - allows light but you can't focus through it
  22. 41. the object vibrating
  23. 42. the study of how sound travels through a spa
  24. 43. the top of the wave
  25. 45. layer filters rut dangerous levels of ultraviolet light
  26. 48. Blacklight - Cause sunburn
  27. 49. waves travel from the source in 1 direction
