- Use the information from the lecture on the rules for ray tracing to complete the ray tracing for the different situations below. This part is graded on completeness so just try it out even if you feel it is wrong. Notice it is important to not get confused between the rules for lenses and mirrors. 1. Consider a concave mirror. An object is placed at various object distances from the mirror. For each case, use ray tracing to determine the following characteristics of the image: * is it real or virtual? n is it upright or inverted? n is it smaller or bigger than the object (or the same size)? n where is the image located? (approximate location – does not have to be exact) Assume a concave mirror with a focal length of f=5cm. Make sure to use a ruler and follow the ray-tracing rules. Draw a diagram for each of the following cases: (a) object is at f/2 (b) object is at f (c) object is at 3f/2 (halfway between center of curvature and focal length) (d) object is at 2f (exactly at center of…Please answer A,B and C and show work on paper and circle answerAll answers require full explanations in complete sentences. The figure below shows a spherical bubble of CO2 gas in a liquid. The index of refraction of the liquid is 1.5 times larger than that of the gas. A light ray in the liquid is incident on the bubble as shown. The black dot identifies the center of the bubble. Draw, precisely, a reasonable ray transmitted into the bubble and explain how you why it looks as you have drawn it. determined

Each segment of the umbrella appears to be a different color. Explain why each section appears to be the color that you see. Answer using 3 to 5 complete sentences.State clearly the principle of Physics that you are using (invoking is the scientific word). Explain (briefly) your methodology. Give any equations that you may use A laminated window consists of Perspex and glass. At the Perspex to glass interface the angle of refraction is 25.00. and the angle of incidence is 150. If the refractive index of the glass is 1.60, what is the refractive index of the Perspex?
