Describe the image.
1. virtual, upright, larger
2. virtual, inverted, smaller
3. real, upright, smaller
4. real, upright, larger
5. real, inverted, larger
6. real, inverted, smaller
7. None of these
8. virtual, upright, smaller
9. virtual, inverted, larger

Explanation / Answer

f=R/2 = 0.43/2 = 0.215 1/i + 1/o =1/f 1/i = 1/0.215 - 1/20.5 so i=0.217 m m=-i/o = -0.217/20.5=-0.0106 i is positive so its real m is negative so inverted and m
