BACK NEXT Chapter 27, Problem 37 GO A hunter who is a bit of a braggart claims that from a distance of 2.0 kom he can selectively shoot either of two squirrels who are sitting 8.7 centimeters apart on the same branch of a tree. What's more, he daims that he can do this without the aid of a telescopic sight on his nine. (a) Determine the diameter of the pupils of his eyes that would be required for him to be able to resolve the squirrels as separate objects. In this calculation use a wavelength of 498 nm (in Vacuum for the light. (b) state whether his daim is reasonable, and provide a reason for your answer. In evaluating his claim, consider that the human eye automatically adjusts the diameter of its pupil over a typical range of 2 to 8 mm, the larger values coming into play as the lighting becomes darker. Note also that under dark conditions, the eye is most sensitive to a wavelength of 428 nm. (a) Number (b) The hunter's daim
