Convex MirrorsConvex Mirrors

• Surface of mirror is curved outward• Spreads out light rays (“diverging”

mirror)• Produces a virtual image that is

upright and smaller than the object

Ray 1: travels parallel to the principal axis and reflects through the focal point

The image appears where the (virtual) reflected rays appear to intersect

Remember:Remember:

The image for a convex mirror is always virtual,

upright and smaller!
