|| Light &
exhibit is a model showing why the sky is blue. This is a phenomenon
called Rayleigh scattering. A clear tube is mounted in front
of a light source with the light shining into the end of the tube.
The light scattered by the tube looks blue near the projector and
get progressively yellower further down the tube. A very orange
"sun" emerges from the tube and is projected onto a screen
on the side of the exhibit. A polarizing filter is attached to the
exhibit table so the user can experiment with the polarized properties
of scattered light.
