wavelength in photosynthesis

[seders99]

Can someone help me understand what wavlength is MOST effective in driving photosynthesis?

I know the energy is greatest at red which is over 700. So if my choices are

420
475
575
625
730

would it be 730? But then I read violet is the best....Any advice?

THANKS

FYI, Gamma and X rays have the shortest wavelength and the longest waves include radio.
