Multiplechoice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points A convergent lens has a focal length of 14 . 5 cm . The object distance is 21 . 6 cm . q h p h f f Scale: 10 cm = Find the distance of the image from the center of the lens. Correct answer: 44 . 1127 cm. Explanation: 1 p + 1 q = 1 f M = h h = q p Convergent Lens f > >p> f f <q < >M > Note: The focal length for a convergent lens is positive, f = 14 . 5 cm. Solution: Substituting these values into the lens equation q = 1 1 f 1 p = 1 1 (14 . 5 cm) 1 (21 . 6 cm) = 44 . 1127 cm . 002 (part 2 of 2) 10.0 points Find the magnification. Correct answer: 2 . 04225. Explanation: M = q p = (44 . 1127 cm) (21 . 6 cm) = 2 . 04225 . 003 (part 1 of 2) 10.0 points A divergent lens has a focal length of 30 cm . The object distance is 12 cm ....
