Section 8
INVESTIGATOR
For the investingation, I looked at two websites provided by the
teacher. They are:
http://www.phys.ufl.edu/~phy3054/light/mirror/applets/convmir/Welcome.html and http://www.factmonster.com/ce6/society/A0859669.html. After viewing the two websites, I developed a
short write up that I will share with my discussion group.
From the second website, I would like to
share that in a convex shape, such as a mirror, the vertex (center) is nearer
to the object than the edges—the mirror bulges toward the object. The image
formed by it is always smaller than the object and always up-right. It is never
real because the reflected rays diverge outward from the face of the mirror and
are not brought to a focus, and the image, therefore, is determined by their
prolongation behind the mirror as in the case of the plane mirror.
The
first website is a great place to go and experience how the convex mirror or
shape works. This web site allows you to
slide the mouse and watch how the incoming rays (angle of incident) and the
reflection rays (angle of reflection) change as the mouse moves.
