Convex & Concave MIRROR Worksheet The same object (height = y) is placed at several different distances s to the left of the same mirror (focal length =). For each case, draw the 3 principal rays to locate the image. Then use the "thin lens" equations to calculate: the image height y' (in terms of y) whether the image is real or virtual the image distance from the lens s' (in terms of s and whether the image is upright or inverted s = tf Diverging & Converging LENS Worksheet The same object (height = y) is placed at several different distances s to the left of the same lens (focal length =). For each case, draw the 3 principal rays to locate the image. Then use the "thin lens" equations to calculate: whether the image is real or virtual whether the image is upright or inverted the Image height y' (in terms of y) the image distance from the lens s' (in terms of sand . f=s A
