A spherical mirror is polished on both sides. When used as a convex mirror, the magnification
is +1/4. What is the magnification when used as a concave mirror, the object remaining the
same distance from the mirror?
I started with:
mconvex = 1/4
mconcave = ?
doconvex = doconcave
hoconvex = hoconcave
I wasn't sure about how to go from here...:
m = hi/ho = -di/do
mconvex = hiconvex/hoconvex = -diconvex/doconvex
mconcave = hiconcave/hoconcave = -diconcave/doconcave
1/4 = hiconvex/hoconvex
hoconvex = 4hiconvex
mconcave = hiconcave / hoconcave
hoconcave = hiconcave / mconcave
4hiconvex = hiconcave / mconcave
mconcave = hiconcave / 4hiconvex
I wasn't sure what to do from here or if I approached this correctly
