1. Draw a ray diagram to help you figure out how the size of the observed image relates to the distance to the mirror. On the picture below draw the rays coming from your head and your toes, and reflected directly into your eyes. 2. Draw the normal line (perpendicular to the mirror surface) from your eyes. Draw the reflected image. 3. On the diagram show what part of the mirror can be covered such that you still see the image. 4. Label the object distance (distance from you to the mirror) s, the image distance s', the height of the person h, and the minimum size of the mirror L. Mirror } ec Charley-Franzwn luatrationsOf.com/34242 5. Refresh your knowledge of the situation's geometry and solve the following problem: express the minimum size of the mirror L in terms of other variables (don't use any numbers, only the labeled variable s, s', and h). 6. Does the minimum size depend on s? What values are important for the minimum size? Discuss it with your instructor. 7. Assumptions: Write a list of all of the assumptions that you made while solving the problem (i.e. write down the factors that you ignored in order to simplify your solution).
