- moron4hire 12y ago"black" is not a wavelength of light. It's the absence of light.
- Cthulhu_ 12y agoWhat I think the question is, is whether it's possible to create a surface of light that reflects only a very specific (range of) wavelengths; that would be quite interesting actually. Highly accurate colors and such.
- femto 12y agoA Dichroic Filter is an example of what you describe. https://en.wikipedia.org/wiki/Dichroic_filter https://en.wikipedia.org/wiki/Dichroic_filter
- femto 12y agoYes. It's the same principle that is used in both microwave and audio anechoic chambers. The pyramidal spikes on the walls [1] of an anechoic chamber are much bigger equivalents of the nanotube spikes being used for light.
