1. Answer each with three significant figures.
a. A 4.50 cm tall object is placed at a distance of (16.8) cm from a convex lens with a focal length of (12.25) cm. Find the size of the resulting image. Give your answer in centimeters (cm) with the correct sign.
b. A 4.50 cm tall object is placed in front a convex mirror with a focal length of (-5.25) cm. If the magnification is 1/9, what is the distance from the object to the mirror. Give your answer in centimeters (cm).
c. A (2.50) cm tall object is placed at a distance of (18.20) cm from a convex mirror. The distance from the mirror to its focal point is (15.40) cm. Find the magnification of the image formed by the mirror. Give your answer with the correct sign.
d. A (7.20) cm tall object is placed in front of a convex lens. As a result, an image is with a height of (– 52.0) is produced on a screen placed (77.5) cm from the lens. Find the focal length of the lens. Give your answer in centimeters (cm) with the correct sign.
