Learning Goals: By the end of this lesson you will be able to
Images in curved mirrors: concave and convex
Solve mirror lab problem in
a virtual lab
Success Criteria: By the end of this lesson you will be able to
A converging (concave) mirror has its focus on the
same side as the object; a diverging (convex) mirror has its focus behind
the mirror.
A light ray that is parallel to the principal axis
of a curved mirror is reflected through the focus
(F); if the mirror is diverging (convex),
parallel rays are reflected away from the virtual focus, which is behind
the mirror.
At least two incident rays are drawn to determine
whether or not an image is formed and, if so, its characteristics. These
rays usually originate from the top of the object.
A converging (concave) mirror produces an
inverted, real image if the object is beyond F; if the object is at F, no image
is formed; and if the object is between F and the mirror, a larger, upright,
virtual image is formed.
A diverging (convex) mirror
always produces a smaller, upright, virtual image.
