Materials Pasco Light Machine and a Sheet of
Graph Paper, reflective surface, concave lens,
convex lens
3
Turn on the Light Machine. Observe the light ray.
4
Line up the machine, and aim a beam directly as
shown toward the reflective surface
5
Now, aim the beam through a concave lens.
6
Which way does the light travel before is hits
the lens?
7
Which way does the light travel after it hits the
lens?
8
Which way does the light THROUGH the lens?
9
Is the light travelling at the same angle before
and after the lens?
10
Align the incoming ray on graph paper. Trace with
a pencil. And use a protractor to confirm your
answer
11
Is this an example of reflection or
refraction. Define both terms!

13
Set the Pasco Sensor for two rays of light
14
Describe the resulting light rays after they pass
through a concave lens. Is this reflection?
15
On your graph paper, trace the rays of light
before and after the lens as it appears in your
experiment. Label the lens and the rays of
light.
16
Describe the resulting light rays after they pass
through a CONVEX lens. Is this reflection?
17
On your graph paper, trace the rays of light
before and after the lens as it appears in your
experiment. Label the lens and the rays of
light.
18
How did the light rays compare when using a
Concave verses a Convex lens?
19
Is this a concave or convex? How do you know?
