Lab Report                                                                Name: ____________________                                                                                                   Section: ___________________     Polarized Light     Part 2 - Crossed Polarizers – Quantitative:   DATA TABLE: Degrees Resistance Light intensity (1/R) 0     15     30     45     60     75     90     105     120     135     150     165     180     195     210     225     240     255     270     285     300     315     330     345     360                 Graph light intensity, 1/R vs. angle between polarization axes. Note that the light intensity indicator 1/R is an arbitrary unit. If we had a true light intensity meter our light intensity units would be in “lux”.     Question:   If you buy polarizing sunglasses how can you be sure they are truly polarized?
