1. Accommodation in the human eye is accomplished by changing the focal length of the lens until the image is in focus on the retina. Vellozians of the planet Velloz have eyes like cameras where their lens (f= 2.50cm) moves to keep the image on the retina. The relaxed eye focuses light from infinity onto the retina. How far must the lens move and in what direction so that a Vellozian can see an object at 25.0 cm from the eye? (Note: This is how eyes of fishes work.)
