Blue is a slightly higher frequency than both red and green but green has a dramatically higher luminosity. Simple arithmetic applied against that less simple luminosity formula allows for contrast comparisons.
- sigmoid10 4y agoWe're still talking about the solar power density here though. Ofc blue is a higher frequency than green, noone disputes that. But you can't technically say green is high(er) in the solar power spectrum.
