Homework Help Overview

The discussion revolves around calculating the ratio of the refraction index for two unknown materials, with one material's property being described in relation to the speed of sound. Participants are exploring the concept of the refraction index and its definition, as well as the relevance of the speed of sound in this context.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the relationship between the speed of sound and the optical index of refraction, with some seeking clarification on the definition of the refraction index itself. There is confusion regarding the appropriate speeds to use in the formula for calculating the index of refraction.

Discussion Status

The discussion is ongoing, with participants providing guidance on the correct interpretation of the formula for the index of refraction. There is a recognition of the need to clarify the terms being used, particularly regarding the distinction between the speeds of light and sound.

Contextual Notes

There appears to be some ambiguity regarding the definitions and relationships between the concepts being discussed, particularly the relevance of the speed of sound in the context of optical properties.

How do u figure out the ratio of the refraction index if you have to unknown materials, that of which, one is 1.25 greater than the speed of sound.

If you are asking about the optical index of refraction, could you please reword your question. You mention "speed of sound"--what's that got to do with it?
 
What is the DEFINITION of "refraction index"?
 
Well to figure out the refraction index the formula is liek n= c/v. Therefore knowing the speed of sound is important. I'm just baffled as to how to get that ratio.

You realize, I hope, that the speeds referred to in that equation for index of refraction are speeds of light, not sound!
