Problem
A convex mirror mounted in a shop for security viewing has radius of curvature R=+2.4m under this chapter's sign convention (light travels left to right, R>0 when the centre of curvature lies to the right of the vertex). A customer stands so=3.0m in front of the mirror.
((a)) Find the focal length of the mirror.
((b)) Find the image distance using the mirror equation.
((c)) State whether the image is real or virtual, and whether the image lies closer to or farther from the mirror than the customer actually stands.
