摘要

A parallel beam of monochromatic light strikes a transparent prism. The cross section of the prism is a regular hexagon. The beam is parallel to the "top" and "bottom" faces of the prism, and points A and B in the diagram are the midpoints of the corresponding edges. After the refraction, two separate parallel beams of light emerge from the prism. What is the minimum index of refraction of the material of the prism that allows such an effect?
