Lab #29.12
Light: Trapping the Light
Fantastic
Purpose
In this activity,
students will investigate the
behavior of light as it passes
from one transparent material to
another.
Discussion
When light
passes from one transparent
material to another, it
undergoes refraction. If the
light crosses the boundary
between the materials at an
angle, the light changes
direction. In this activity,
you will see how the
direction changes when light
travels from air to water
and when light travels from
water to air.
Required Equipment
Light beam
viewing tank (or equivalent),
opaque white tank insert,
stirring rod, access to water
access to scattering agent
(Mop-N-Glo™, Pine-Sol™, powdered
milk, or equivalent), laser
pointer
