PHY 114 Lecture 16: Lecture 16
Document Summary
A defect in a diamond appears to be 2. 00 mm below the surface when viewed from directly above that surface, as given by the diagram below. The previous result can also be determined through snell"s law and. The actual depth of the defect is y and it appears to be at a depth of y" The angles (cid:2869) and (cid:2870) are related by snell"s law: (cid:2869) sin((cid:2869))=(cid:2870) sin ((cid:2870)) (cid:4593) tan((cid:2870))= tan ((cid:2869)) (cid:2869) (cid:4593) cos((cid:2869))=(cid:2870) cos ((cid:2870)) angles (cid:2869) and (cid:2870) are nearly 0 degrees. As long as you are directly above the defect and its image, the. Rays from only a narrow range of angles will enter your eyes. The actual depth of the defect in the diamond is then: A diverging lens will bend light away from the principal axis. A converging lens will bend light toward the principal axis.
