Document Summary
Phys1070: intro physics for life sci - lecture 14: optics questions and review. A: causes different colours to be brought into different focus due to the variation of index refraction or speed of light of material. A: - one which can be focused on a screen an image through which light rays actually pass an image formed on the opposite side of the lens from the object. A: the process of adjusting the lens curvature by which the eye can focus sharply at different distances. Q: a person has a nearpoint of 1. 20m. P= 1/p +1/q 3. 00 = 1/p + 1/-1. 20. 1/p = 3. 833 p = 1/ 3. 833 p = 0. 260 m b. Q: light ray passes from air into water making an angle (in air) with normal of (30 degrees ( 1)): what is the angle the ray makes with the normal in water ( 2)? n1sin 1=n2sin 2. What is the speed of light in water? n=c/v v=c/n.
