Subject: Wavelengths of light required for photosynthesis.

Hi,

See subject, what wavelengths of light does photosynthesis require, I seem
to remember that there 
were two that it focused on 580 & another, also, is this a dead-center
number, or does this really mean that chlorophyll will react to plus/minus
20 NM in any direction? 

Thanks in advance, I really appreciate it.

I speak for myself, not for Tandem, unless I'm speaking for Tandem,
in which case, I speak for Tandem, but I don't speak for Tandem, so
I speak for myself, just little ol' me, and nobody else. Got it?

Go to the library, and check out any book on plant physiology, and you
should find a nice chapter on the subject.

Regards,

Steve

Photosynthesis requires light between 380 and 700 nm - also known as PhAR - 
Photosynthetically Available Radiation. The spectrum as two tops: A large one 
around 450 nm and a smaller one around 650 nm. You can look the spectrum up in 
any plant physiology text book.
