Warning:
CHOKING HAZARD-Small Parts. Not for children under 3 years. It must be accompanied by a
parent or teacher while assembling.
Experimental principle:
The principle of keyhole imaging
is that the light in the same
uniform medium, without the
interference
of
gravitational
action, will move along the
straight line propagation. That is
namely the straight line propaga-
tion of light. When a board with
small holes is used to block
between the object and the wall,
the reflection of the object will be
formed when turn on the bulb.
We
call
this
phenomenon
keyhole imaging.
There are all kinds of constella-
tions on the slide. Let's get to see
them.
