The key difference is that instead of focusing the light on a strip of photochemical film as in traditional cameras, digital cameras use an image sensor, called a charge coupled device (CCD), to capture the image.
Because radiation from the Crab nebula is so energetic, the electrons that created it must have been travelling very close to the speed of light so close that the difference between the two speeds would bump up against Planck-scale graininess, and show up in the spectrum of the radiation.
The color of the light is mathematically determined by the energy level difference.
Since the speed of light through a cable is consistent, the difference is entirely in the length of its path.
Blue light also reduced EEG activity associated with sleepiness, but the difference wasn't statistically significant.
In terms of civic knowledge (questions 1 and 2), the authors found a significant difference in learning outcomes by country, which should probably be seen in the light of the widely different approaches to civic education in the countries.

So real that they even preform tests under two different light conditions because everyones household lamps are a bit different and that can make a big difference on how the colors appear.
