Compute the following questions given below:
Question I: What is the focal length of the eye-lens system when viewing an object at infinity? Assume that the lens-retina distance is 1.9 cm.
Question II: What is the focal length of the eye-lens system when viewing an object 31cm from the eye? Assume that the lens-retina distance is 1.9 cm.
Please use as much detail as possible in your answer. Thank you.
