Question
Chapter 2.1, Problem 1TQ
Summary Introduction
To review:
The perception of an upright image followed by the formation of an inverted image on the retina.
Introduction:
The perception of objects in the physical world especially the microbial world of bacteria, viruses or other microorganisms is limited for the human eye. The development of microscopes improves our ability to perceive objects. All technical developments follow the basic principles of physics and the sensory system of the eye and the brain.

- You are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this? a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it. b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations. c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations. d) all of the above.
