11. The flashes are due to labradorescent internal reflections , sometimes called a moonstone effect. 12. This phenomenon is called total internal reflection and allows for fiber optics technology. 13. The polarization of the rainbow is caused by the internal reflection . 14. This fiber has an internal reflection with a 70-degree deflecting angle. 15. Almost any dielectric material can act as a perfect mirror through total internal reflection . 16. The natural fibers of ulexite conduct light along their long axes, by internal reflection . 17. This is accomplished through frustrated total internal reflection , also known as evanescent field coupling. 18. It has a color of pale rose in reflected light with no internal reflection . 19. The nanowire-based morphology offers reduced internal reflection , facile strain relaxation and increased defect tolerance. 20. Dielectric waveguides use total internal reflection to confine light in a high index region.
