- Show that when a ray of light is incident on the surface of a transparent medium at polarizing angle, the reflected ray and the refracted ray are at right angles to each other.What is the index of refraction of a material for which the wavelength of light is 0.658 times its value in a vacuum? Identify the likely substance. The substance is most likelyThe display windows of some department stores are slanted slightly inward at the bottom. This is to decrease the glare from streetlights or the Sun, which would make it difficult for shoppers to see the display inside. Sketch a light ray reflecting from such a window to show how this technique works.
