Below is a ray diagram showing the refracted ray as it travels across the diamond. The dashed line represents the normal to the surface between the water and the diamond.

though you don't know the exact direction of the incident ray yet, you can estimate it by applying step 3 in the Tactics Box above. Use your estimate to complete the ray diagram.

To practice Tactics Box 18.1 Analyzing refraction. If a ray refracts between medium 1 and medium 2, having indices of refraction n1 and n2, the ray angles θ1 and θ2 in the two media are related by Snell's law, n1sinθ1=n2sinθ2. This law becomes a central idea in a procedure for analyzing refraction problems, as explained in the following Tactics Box. Draw a ray diagram. Represent the light beam with one ray. Draw a line normal to the boundary. Do this...
A student is riding their bike when they come across a turn in the form of a circular arc of radius R 3.0m as pictured in the diagram below and travel along this arc in the clockwise direction. At one point along this trajectory (the origin of the given coordinate system) it makes sense to define the Cartesian coordinate system shown where the x-axis is tangent to the trajectory and the y-axis is perpendicular to it. At this point the...
Read about Cokes strategy in Africa in the article below and discuss the ethics of selling soft drinks to very poor people. Is this an issue that a company like Coke should consider? Africa: Coke's Last Frontier Sales are flat in developed countries. For Coke to keep growing, Africa is it By Duane Stanford Piles of trash are burning outside the Mamakamau Shop in Uthiru, a suburb of Nairobi, Kenya. Sewage trickles by in an open trench. Across the street,...
