  9. 19. adjustable opening in the eye through which light enters.
  10. 22. study of the relations between the physical characteristics of stimuli and our psychological experience of them.
  11. 23. energy spectrum that contains visible light.
  12. 25. theory that the region of maximum vibration along the basilar membrane is the basis of pitch discrimination.
  13. 26. visual receptors that are concentrated in the periphery of the retina.
  14. 27. part of the eye that changes shape to focus images on the retina.
