Material for this Lab Experiment 9 Manual General Lab Documents TOC and Introduction Appendix A: Error Analysis for the Physics Labs Appendix B: Introduction to Spreadsheets and EXCEL 2010 Problem Statement: Consider the following: Calculate Brewster\'s angle in degrees for glass with an index of refraction of n = 1.5 Numeric : A numeric value is expected and not an expression. phi_B = _________

Solution

Brewsters law
n=tan b
where
n= refractive index of 1st medium w.r.t. 2 medium
b= Brewster angle
in the A case
medium 1 is air & medium 2 is glass
n=n2/n1=1.5/1.0=1.5

1.5=tan b
b=56.3 deg
