- When light goes from an unknown plastic into water (n = 1.33), it exhibits total internal reflection at a critical angle of 57.7o. What is the index of refraction of the plastic?The 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.A ray of light passes through a prism, making the minimum angle of deviation. The rays enter and emerge at 7° from the normal to the surface. What is the index of refraction of the material, if the prism angle is 50°?
- What is the critical angle for total internal reflection for glass in air? Assume that nglass= 1.50 and nair = 1.00.At what angle inside glass is light totally internally reflected? At what angle inside a diamond is light totally internally reflected?true or false? The critical angle for a material is the angle at which all light striking at that angle or greater will experience total internal reflection.
- A thin spherical glass shell in air is filled with an unknown liquid. A parallel light beam is incident on the shell, and it is observed that the light is brought to focus on the surface of the shell directly opposite. What is the reflective index of the liquid? The correct answer is 2, but I do not understand how to get this answer.A fish tank filled with water is made of flat glass walls of n = 1.74. What is the maximum angle of incidence for a light ray within the water to strike the glass wall and still emerge to the outside air?
