Extracting thickness of glass and index of refraction from Cartesian Graph

  1. Oct 1, 2012 #1
    1. The problem statement, all variables and given/known data
    I made a graph in Excel which graphs (1/x^2) vs (1/cos^2 (angle of incidence)).
    From the graph I am supposed to analyze the slope and intercept of the straight line.
    I made a trendline which came out to be y=mx + b = (-0.0084)x + 5.54.
    From this equation I'm supposed to understand what the thickness of the mirror was in the experiment and what the index of refraction of the mirror is.


    2. Relevant equations



    3. The attempt at a solution
