PIRA: 6A44.40
Equipment
- Lumirod
- Optical fiber principle box
- Spectra Physics 155 Laser (or small maglite can be used)
- Include ‘internal reflection tube’
Instructions
- Turn on the laser and direct the beam at the end of the coil. Light emerges from coil perpendicular to the entry beam.
- The straight and curved rods can be used to show how optical fibers bend a light beam to produce total internal reflection
