Multiple-choice 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 cm . The object distance is 32 . 3 cm . q h p h f f Scale: 10 cm = Find the distance of the image from the center of the lens. Correct answer: 24 . 7104 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 cm. Solution: Substituting these values into the lens equation q = 1 1 f- 1 p = 1 1 (14 cm)- 1 (32 . 3 cm) = 24 . 7104 cm . 002 (part 2 of 2) 10.0 points Find the magnification. Correct answer:- . 765027. Explanation: M =- q p =- (24 . 7104 cm) (32 . 3 cm) =- . 765027 . 003 (part 1 of 2) 10.0 points A divergent lens has a focal length of 18 cm . The object distance is 25 . 4 cm . f f q h p h Scale: 10 cm = Find the distance of the image from the center of the lens. Correct answer: 10 . 5346 cm. Explanation: 1 p + 1 q = 1 f M = h h =- q p Divergent Lens f < >p> f <q < <M < 1 Note: The focal length for a divergent lens is negative, f =- 18 cm. Solution: Substituting these values into the lens equation q = 1 1 f- 1 p nguyen (jmn727) oldhomework 36 Turner (59070) 2 = 1 1 (- 18 cm)- 1 (25 . 4 cm) =- 10 . 5346 cm | q | = 10 . 5346 cm . 004 (part 2 of 2) 10.0 points Find the magnification. Correct answer: 0 . 414747. Explanation: M =- q p =- (- 10 . 5346 cm) (25 . 4 cm) = . 414747 ....
