4. (a) Use ray tracing to find the image of a 3 cm arrow in a convex spherical mirror of focal length 2 cm, when the arrow is 2 cm in front of the mirror and perpendicular to the axis. A scale is provided for your convenience. Label the focal point F and the center of curvature C of the mirror, and the optical axis on your drawing. * (b) Is the image upright or inverted? Larger or smaller than the object? Is the image real or virtual and can you justify your answer? (Circle the correct answers). (6 pts) 3 4.
