Refraction at Flat Surfaces: Blackboard Optics — Refraction

Photo of the Demonstration at the University of Texas at Austin when used in a darkened room.

Photos shows other variations of this demonstration.

Instructions / Notes:

• Faculty: Room lights must be dimmed for students to see the refracted rays.
• Optics Board light sources are set to project rays through lucite prisms.
• The light sources include an incadescent ray box and a set of parallel lasers.
• The bottom most light source, (hiding in the photo below), is set up with a single slit - it projects through a small prism to show a spectrum.
