spherical convex mirror given in the template on the next page. To
find the required normal lines of the mirror’s surface, trace a
thin line from the center of curvature through the mirror. A sample
normal line (dotted) has been provided for you. It is best to use a
protractor to make sure that the incident and reflected angle of
your rays are exactly the same.
2. Now that you have found the focal point, place an object on
the optical axis. Recall that when dealing with mirrors, all
distances are measured with respect to the so-called vertex: the
point where the mirror intersects the optical axis. Use the
following values: Object Distance: do = 6 [cm] Object Height: ho =
2 [cm]
3. Determine the image distance, di , image height, hi and
magnification, M, by carefully graphing the parallel and chief rays
and measuring the resulting image. Be mindful of the image
orientation. The process is similar to the one we use with lenses,
except that the parallel ray passes from the tip of the object to
the mirror and is then reflected through the focal point, and the
chief ray passes from the tip of the object through the center of
curvature. Their intersection determines the image location.
