A light bulb is placed 10 cm from a plane mirror, which faces a convex mirror of radius of curvature \(8 \mathrm{cm}\) The plane mirror is located at a distance of \(30 \mathrm{cm}\) from the vertex of the convex mirror. Find the location of two images in the convex mirror. Are there other images? If so, where are they located?

Because the eye is a light receptor and lasers produce light of extreme brightness, exposure of the eye to laser light can cause serious and lasting damage.

What is the focal length of a magnifying glass that produces a magnification of 3.00 when held \(5.00 \mathrm{cm}\) from an object, such as a rare coin?
