- Assuming light enters from the left. Draw (a) a flat mirror, (b) a concave mirror and (c) a convex mirror from a side view. Mark the focal point of each mirror.You are standing 4m from a convex security mirror in a store. You estimate the height of your image to be half of your actual height. Estimate the radius of curvature of the mirror, and interpret its sign.A plane mirror receives a light ray entering at 30° relative to the surface of the mirror. This is the angle of incidence. true or false
