Curated by: But Why? (50 videos)
We only see radiation with 400nm to ~700nm. It seems so strange when the electromagnetic radiation spans factors and factors of 10. Why such a small slice? Why just Red, Green, and Blue? and more importantly... how? Note: At 6:30 I say tetrachromats don't see 'more' colors than trichromats. That was a mistake, I meant to say 'New' colors. They certainly see more. Just not new ones. Unless you consider hues and shades new colors.
