Green Xenon Posted January 23, 2011 Share Posted January 23, 2011 Hi: I have two favorite wavelengths [colors] of visible light. These two wavelengths of light [when emitted monochromatically and perhaps together as well]: 1. Cause the least amount of stimulation [hopefully none] of the rods of the average human retina 2. Cause the least amount of stimulation [hopefully none] of the blue cones of the average human retina Wavelength-1 is reddish-green while wavelength-2 is greenish-red. Both wavelengths [even if view separately] will stimulate both red and green retinal cones, hence the terms “reddish green” and “greenish red”. However, reddish-green causes more stimulation of green cones than red cones, while greenish-red causes more stimulation of red cones than green cones. Therefore, when viewing wavelength #1, the average human will likely express perception of green. However, when viewing wavelength #2, the average human will likely express perception of red. What wavelength of light most closely fits wavelength #1? What wavelength of light most closely firs wavelength #2? Thanks, Green Xenon Link to comment Share on other sites More sharing options...

Thanks, Green Xenon Take your pick: Looks like anything longer than 600nm has negligible blue and rod response. Link to comment Share on other sites More sharing options...
