Curved Mirrors

Images in Mirrors S ize, A ttitude, L ocation, T ype Size –Is the image bigger, smaller or the same size as the object? Attitude –Is the image right side up (upright) or upside down (inverted)?

Images in Lenses Location –Closer than, farther than or the same distance as the object to the mirror. Type –Is the image real or virtual? –Virtual image = an image formed by light coming from an apparent light source. Light is not arriving at or coming from the actual image location.

Terminology C = centre of curvature R = radius of curvature V = vertex PA = principal axis F = principal focus f = focal length Focal plane = rays coming from different angles will form images in the focal plane

Some Rules All distances are measured from the vertex of a curved mirror. Distances of real objects and images are always positive Distances to virtual objects and images are always negative. Heights for both objects and images above the PA are positive, heights below the PA are negative.

Converging Mirror

Diverging Mirror

Rules for Curved Mirrors A ray that is parallel to the principal axis is reflected through (or as if it had gone through) the principal focus – real or virtual. A ray passing through (or appearing to pass through) the principal focus is reflected parallel to the principal axis. A ray passing through (or appearing to pass through) the centre of curvature is reflected back along the same path.
