The original poster attempts to calculate the speed of light in a diamond given its refractive index. The problem involves understanding the relationship between the speed of light in a vacuum and its speed in a medium with a specific refractive index.
The discussion is exploring the definitions and relationships involved in the problem, with participants providing guidance on focusing on the definition of the refractive index rather than Snell's law. There is an ongoing exchange about the relevance of these concepts.
There is a focus on clarifying the definitions and relationships between refractive index and light speed, with some participants expressing confusion about the role of Snell's law in this context.
