A 1.80-m-tall person stands 2.80 m from a convex mirror and notices that he looks precisely half as tall as he does in a plane mirror placed at the same distance.
What is the radius of curvature of the convex mirror? (Assume that sinθ≈θ.) [Hint: The viewing angle is half.]
Express your answer with the appropriate units.
