You see an upright, magnified image of your face when you look into a magnifying cosmetic mirror. Where is the image? Is it in front of the mirror's surface, on the mirror's surface, or behind the mirror's surface? Explain.
A -tall object is in front of a converging lens that has a focal length.
Use ray tracing to find the position and height of the image. To do this accurately, use a ruler or paper with a grid. Determine the image distance and image height by making measurements on your diagram.
Calculate the image position and height. Compare with your ray-tracing answers in part .
Consider one point on an object near a lens.
a. What is the minimum number of rays needed to locate its image point? Explain.
b. How many rays from this point actually strike the lens and refract to the image point?
