Light ray entering a semicircular glass block toward its center.
Light ray entering a semicircular glass block toward its center.
A monochromatic light ray enters a semicircular glass block with index of refraction \(n = \sqrt{2}\) surrounded by air (\(n = 1.00\)). The ray enters perpendicular to the curved surface and is directed toward the center of the flat boundary, making an angle of \(30^\circ\) with the normal to the flat boundary inside the block. Which of the following correctly pairs the behavior of the light ray at the flat boundary with the angle of the resulting ray relative to the normal?
