Measuring Speed of Light with Glass Plate

Click For Summary

Homework Help Overview

The discussion revolves around determining the speed of light using a glass plate, specifically focusing on the relationship between the index of refraction and the speed of light in different mediums.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants explore whether the goal is to find the speed of light in a vacuum or within the glass plate, and discuss the implications of the index of refraction in this context.

Discussion Status

Some participants have clarified the distinction between the speed of light in vacuum and in the glass plate, while others have provided a formula relating these concepts. The discussion is ongoing with various interpretations being considered.

Contextual Notes

There is mention of specific values for the index of refraction and the speed of light in vacuum, but the exact experimental setup or additional data has not been detailed.

How can I determine the speed of light from a glass plate? I have the the numbers that I compared the average experimental value of the index of refraction with the general range of the index of refraction of glass.

are you trying to find out speed of light though a glass plate? I am not sure what your question is.

yes, that's correct.
 
Is the problem to find the "speed of light (in vacuum)" or "the speed of light in the glass plate". The index of refraction is the ratio of speed of light in the glass plate to the speed of light in vacuum.
 
V = C/N... c being speed of light (3x10^8) and N being being whatever the index of refraction is of the glass.
