Dracula has a hole in his roof,
the sun is rising and he needs your help quickly!
Participate in the following activity and learn how
to reflect the incoming light out of his
house.

|

Small
mirror
Protractor
Flashlight

Setup the mirror and the
protractor as illustrated
Use the flashlight to shine a
beam as the ray in the angle of incident and note
the angle of the beam on the protractor. The ray
that strikes the mirror is called the incident or
striking ray.
|
|
|
|
|
The ray that is bounced back by
the mirror is called the reflected ray. Does the
beam that is reflected in the angle of reflection
show the same degree on the protractor?
|
|
|
|
|
The angle between the incident
ray and the surface of the mirror is called the
angle of incident. Whereas the angle between the
reflected ray and the surface of the mirror is
called the angle of reflection. If you know one of
the angles you should be able to figure out the
other angle. Use the the mirror and protrator along
with what you've just learned to reflect the
incoming sunlight out of Dracula's house before its
too late!
