| Jan 7, 2016 at 0:08 | comment | added | Quark | @igael Then how is it releasing the energy? As heat? | |

| Dec 30, 2015 at 20:45 | comment | added | Carl Witthoft | Very few polarizers reflect light. your everyday sunglasses absorb light, leading to extremely minor heating. However, it is not "said that.. absorb light" . What is said is that only one polarization is transmitted. | |

| Dec 30, 2015 at 20:23 | comment | added | Gyro Gearloose | I guess that a polarizer just reflects the light, but there may be types that absorb it. +1 for a question that I never thought of. | |
