| 説明 | if i were a real physicist, i would just know that rainbows are polarized, but i wasn't sure, and wanted to do the experiment. upper photos are essentially right out of the camera (some minor cropping), the difference between the left and the right is the orientation of my polarizer. the lower photos are the same as the upper except that i digitally cranked up the contrast to show off an effect i've sometimes seen in rainbows, that it's not just ROYGBIV, but more like ROYGBIVBIV. you may have to look at a larger version of this image to see that. |
