Re: Dumb Question (optical properties of plants)

Where is the best place to ask questions about which light
wavelengths/colors are used by plants to photsynthesize and
which are wasted? It really isn't an optics question, but
I didn't see any biology group that looks right either...

Try: sci.bio.botany for questions about plants.

A chart of the relative absorbance versus wavelength for chlorophyll a and b
can be found at:

(It appears that the vertical axis is not labeled.)

Use Google and the keywords: chlorophyll absorbance spectrum results in
many links. A plot with a labeled vertical axis is shown at:

Hope this helps (my background is primarily in physics, not botany).
