Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points The thin composite lens has | R 1 | = R and | R 2 | = R 2 , as shown in the figure. R 1 R 2 n 2 n 1 The lens has focal length 1. f = n 2 n 2- n 1 R . 2. f = n 1 4 ( n 1- n 2 ) R . 3. f = n 2 2 ( n 1- n 2 ) R . 4. f = n 1 2 ( n 2- n 1 ) R . 5. f = n 1 n 1- n 2 R . 6. f = n 2 n 1- n 2 R . 7. f = n 1 n 2- n 1 R . 8. f = n 2 2 ( n 2- n 1 ) R . 9. f = n 1 2 ( n 1- n 2 ) R . 10. f = n 1 4 ( n 2- n 1 ) R . 002 (part 1 of 2) 10.0 points A concave spherical mirror has a radius of cur- vature of 32 . 2 . The object distance is 8 . 2 cm . h q h p f R Scale: 10 cm = Find the magnitude of the image distance. Answer in units of cm. 003 (part 2 of 2) 10.0 points Find the magnification. 004 (part 1 of 2) 10.0 points A convergent lens has a focal length of 25 cm . The object distance is 13 . 9 cm . f f q h p h Scale: 10 cm = Find the distance of the image from the center of the lens. Answer in units of cm. 005 (part 2 of 2) 10.0 points Find the magnification. 006 (part 1 of 3) 10.0 points Batman and Robin are attempting to escape that dastardly villain, the Joker, by hiding in a large pool of water (refractive index n water = 1 . 333). The Joker stands gloating at the edge of the pool. (His makeup is water- soluble.) He holds a powerful laser weapon y 1 = 1 m above the surface of the water and Brannon (blb675) – HW #12 – Shih – (58250)...
