Use the formulas 1/f = 1/so + 1/st and M = hi/ho = –si /so for Problems 1–8.
1. Given so = 1.65cm and si = 6.00cm find f.
2. Given f = 15.0cm and si = 3.00cm find so.
3. Given si = 1.45cm and f = 10. 0cm find so.
4. Given si = –10.0cm and f = –5.00cm find so
5. Given so = 7.35cm and si = 17.0cm find f.
6. Given hi =2.75cm, ho = 4.50cm and si = 6.00cm, find so.
7. Given ho = 12cm, si = 13cm and so = 25cm, find hi.
8. Given hi = 3.50cm, ho = 2.50cm, si = 15.5cm find so.
9. If an object is 2.50 m tall and 8.60 m from a large mirror with an image formed 3.75 m from the mirror, find the height of the image.
