Refraction and internal reflection. In this photograph a beam from a Helium-Neon laser (633 nm) enters a right angle prism from below. The beam refracts at the air-glass interface according to the Snell's law. At the hypotenuse,some light is refracted into the air and some is reflected back into the glass. The reflected beam then exits the prism to the right,exhibiting refraction again | |
