Reminders: Real images are on the opposite side of the lens as compared to the object. dois positive wherever it is placed. When the image is on the opposite side of the lens it is real and it has a positive d. . When the d, is negative, it means the image is on the same side of the lens as the object. 1. A 4.00-cm tall light bulb is placed at a distance of 45.7 cm from a converging (convex) lens having a focal length of 15.2 cm. Determine the image distance and the image size. (C - /2) (K/U -2) 2. A lens forms an image that is 12 cm from the lens and on the same side of the lens as the object (virtual). The image is upright and 3.0 cm high. If the object is 4.0 cm high, find: (C - /2) (K/U -3) a) d, = ? b ) do = ? c) is the lens concave or convex? 3. A camera has a converging lens with a focal length of 1 cm. You are taking a picture of a person who is 2 meters tall and stands 3 meters away from the lens. (K - 2) a) How far from the lens should the film be located? b) How tall is the person's image on the film?4. A converging lens has a focal length of 20.0 cm. Locate the images for object distance of 40.0 cm. State whether the image is real or virtual and upright or inverted, and find the magnification. (C - /2) (K/U - 2) 5. Draw the image found when a 1cm object is placed 5cm from a converging lens. The focal length is 2.5cm. Complete the S. A. L. T. for each. (C - /2) (K/U - 2) 6. Draw the image found when a 1.5cm object is placed 4cm from a diverging lens. The focal length is 3cm. Complete the S. A. L. T. for each. (C - /2) (K/U -2)
