  1. 5. The location of objects by reflected sound, in particular that used by animals such as dolphins and bats
  2. 8. Volume the magnitude of sound
  3. 9. Each of the lines in which light (and heat) may seem to stream from the sun or any luminous body, or pass through a small opening
  4. 10. Sound humans can't hear
  5. 12. The primary additive colors for light are red, green, and blue; the primary subtractive colors (which give the primary additive colors when subtracted from white light) are magenta, cyan, and yellow
  6. 15. Not able to be seen through; not transparent
  7. 16. A musical tone that is a part of the harmonic series above a fundamental note and may be heard with it.
  8. 17. A membrane of the middle ear that vibrates in response to sound waves; the tympanic membrane.
  9. 20. tone The tone that represents the frequency of a vibrating object such as a string or bell.
  10. 22. Capable of transmitting light so that objects or images can be seen as if there were no intervening material
  11. 23. The spiral cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations
  12. 24. A graph representing a sound, showing the distribution of energy at different frequencies
  13. 26. The properties or qualities of a closed area that determine how sound is transmitted in it.
  14. 28. The degree of compactness of a substance.
Down
  1. 1. The degree of highness or lowness of a tone.
  2. 2. Sound having an ultrasonic frequency
  3. 3. Prolongation of a sound
  4. 4. Effect A change in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.
  5. 6. aka voice box
  6. 7. (Of a substance) allowing light, but not detailed images, to pass through; semitransparent
  7. 11. color A color produced by mixing two additive primary colors in equal proportions. The secondary colors are cyan (a mixture of blue and green), magenta (a mixture of blue and red), and yellow (a mixture of green and red)
  8. 12. The natural coloring matter of animal or plant tissue
  9. 13. The measurable amount of a property, such as force, brightness, or a magnetic field.
  10. 14. colors Colors directly opposite each other in the color spectrum, such as red and green or blue and orange, that when combined in the right proportions, produce white light
  11. 18. A unit used to measure the intensity of a sound
  12. 19. Either of the passages in the outer ear from the auricle to the tympanic membrane
  13. 21. The ability to resume its normal shape after being stretched
  14. 25. sounds that are combined to sound appealing
  15. 27. A system for the detection of objects under water and for measuring the water's depth by emitting sound pulses and detecting or measuring their return after being reflected
  16. 29. A sound or series of sounds caused by the reflection of sound waves from a surface back to the listener
