Question

A convex mirror has a radius of curvature whose magnitude is 59cm. The mirror is positioned on a horizontal optical bench with its front surface at 0cm. A 11.0cm long fluorescent lamp oriented vertically is placed at +106cm.

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 206cm from the plane mirror, how tall would the image be?



Explanation / Answer

Image distance(v) / Object distance(u) = Image size / Object size 1/f = 1/u + 1/v plugin values
