The Optics Physlet models mirrors, lenses, and changes in index of refraction for various types of light sources. This simulation shows how light is trapped inside a fiber optic cable. The light beam can be dragged into and out of the medium and its angle adjusted by click-dragging the white hot spots. Click drag away from a hot spot to measure an angle.
Find the index of refraction of the blue medium.
