The Human Eye THE HUMAN EYE: While digital camera form imageswith pixels, the human eye forms images with rods and cones thatlie on the retina. If two point objects close together are to beseen as two distinct objects, the images must fall on the retina ontwo different cones that are not adjacent. That is, there must be acone between them. Assume that the cones are sensitive to awavelength of 550nm. If the iris is about 5mm in diameter, and wecan model the human eye as a sphere with roughly a 25mmdiameter,
a. What is the minimum separation between two objects at adistance of 2rn away from the eye that we can resolve at thiswavelength?
b. What is the distance between the two cones on the retina?
