A convex mirror has a radius of curvature whose magnitude is 41 cm. The mirror is positioned on a horizontal optical bench with its front surface at 0 cm. A 11.5 cm long fluorescent lamp oriented vertically is placed at +101 cm. What is the focal length of the mirror?
At what distance from the mirror can we find a sharp image of the lamp?
How tall is the image of the lamp?
If the convex mirror were replaced by a plane mirror and the lamp moved to 206 cm from the plane mirror, how tall would the image be?
