The index of refraction in a certain precious transparent stone is 2.35. What is the speed of light in that stone?
Answer to relevant QuestionsThe indices of refraction for zircon and fused quartz can be found in Table 22.1. (a) The speed of light in fused quartz is (1) greater than, (2) less than, (3) the same as the speed of light in zircon. Explain. (b) ...(a) For total internal reflection to occur, should the light be directed from (1) air to water or (2) water to air? Explain. (b) What is the critical angle of water in air? The critical angle between two materials is 43o. If the angle of incidence is 35o, what is the angle of refraction? (Consider that light can travel to the interface from either material.) A submerged diver shines a light toward the surface of a body of water at angles of incidence of 40o and 50o. Can a person on the shore see a beam of light emerging from the surface in either case? Justify your answer ...Two upright plane mirrors touch along one edge, where their planes make an angle of α. A beam of light is directed onto one of the mirrors at an angle of incidence of β(β < α) and is reflected onto the other mirror. (a) ...
