An equilateral triangle with a horizontal base and a vertex at the top represents the cross section of a prism. The interior of the triangle is labeled \(n = 1.5\). The region outside the triangle is labeled \(n = 1.0\). A single horizontal ray with an arrowhead pointing to the right is incident on the upper half of the left slanted face of the triangle. No other labels, lines, text, or axes appear.
A light ray in air incident on an equilateral glass prism.
A monochromatic ray of light traveling in air is directed horizontally toward the slanted left face of a solid glass prism with an equilateral triangular cross section, as shown. The index of refraction of the glass is \(n = 1.5\), and the index of refraction of the surrounding air is \(n = 1.0\). Which of the following ray diagrams correctly represents the path of the light ray as it enters, passes through, and emerges from the prism?
