| 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! |
