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?
