3. Use d
o
and d
i
to calculate the magnification and record it in Table 14.1.
Questions
1. Is the magnitude of d
i
less than or greater than d
o
? If you replace the convex mir-
ror with a plane mirror, what would be the relationship between d
i
and d
o
?
2. Is M positive or negative? How does this relate to the appearance of the image?
3. Draw a scale diagram showing the half-screen, mirror, viewing screen, and vir-
tual image. Label every part.
