Funny Mirrors
Question:
Can you alter the body shape
of Tang Xiao-shan?
Instructions:
1. Look
through the hole on the head of Tang Xiao-shan and observe
her images in the mirrors.
2.
Which mirror will make her look fatter, slimmer, higher
or shorter?
Why?
To an observer standing in
front of a plane mirror, the image formed has always the
same size as the observer. It appears smaller only because
it is farther away. On the other hand, convex mirrors
always form diminished images, so they are ideal for applications
in which a broad field of view is required. The size of
images formed by concave mirrors depends on how far the
objects are located from the mirror foci.
