I've got two miscellaneous science questions. 

1) On TV's and computers screens, why is it RGB (red, green, blue)
instead of RYB (red, yellow, blue) the primary colors?

2) Some light wave length produces the color green. A mixture of
the wave lengths of blue and yellow also produces green.
Even though these two greens are indistinguishable to our eyes, are there
(could there be) instruments that distinguish them?
