A glass block with index of refraction n = 1.7 is immersed

Last updated: 7/6/2022

A glass block with index of refraction n = 1.7 is immersed in an unknown liquid. A red beam of light traveling in the glass is incident on the top of the block. As shown in the diagram, there is no refracted ray. a) Is the index of refraction of the liquid ny larger than, smaller than, or equal to the index of refraction of the block? Explain your reasoning. b) Determine an inequality for the index of refraction n (this should be a pure number). Explain why this is an inequality instead of an equality.
