The wavelength most effective in conducting photosynthesis is 420nm.
^^ Actually, 420nm is on the blue side of the spectrum, which makes up between 1 and 10% of the light needed for photosythesis. There is a plateau on the blue side when comparing blue wavelength effects on photosynthesis, and 420nm is right on the edge of it. 430nm would be more in the middle of the plateau, making it the safer bet.
Plants need red light, and lots of it. Red light contributes to over 90% of photosynthesis. You can't grow plants on just blue light. Seems to be the most efficient wavelength of red light, for photosynthesis, is between 660nm and 680nm, and not higher. Unlike blue, there is no plateau when comparing red wavelength effects on photosynthesis, so there is a more broad answer, depending on the plant.
It seems though, if working with LEDs, that 630nm are more mass produced (cheaper). So you can just use those instead, or couple them with far red light (infrared), 730nm, to stimulate PFR, germination. Far red light depends greatly on what you are growing though, read up on it.
I'm no expert, but the first answer wasn't very good.
^^ Overall, I would agree with this answer. However, it is possible to grow a plant using only blue light. Blue light is required for the vegetative growth of plants. I have been able to grow basil using blue LED lighting on a 20 hour cycle. This is fine for herbs. If you wish for your plant to flower you will need red light at the wavelength described in the previous answer. It is also possible to grow plants using only a red wavelength. Although, from what I hear the plants will look a little thinner than normal but the quality of tast should be the same.
The most effective wavelengths of light in driving photosynthesis are blue (430-450 nm) and red (640-680 nm) light. These wavelengths are absorbed most efficiently by chlorophyll a and b, the pigments responsible for capturing light energy in photosynthetic organisms. Ultraviolet light (UV) and green light are less effective in driving photosynthesis.
The absorption spectrum for chlorophyll peaks at indigo (violet-blue) and red light. These wavelengths are ABOUT 400-450 and 600-700. The colors that bounce back and are not absorbed are primarily green, giving plants their trademark color.
The wavelength of 475nm and 650nm are most effective in driving photosynthesis.

What wavelength of light is the least effective in driving photosynthesis?
Green light is the least effective in driving photosynthesis because chlorophyll pigments absorb more strongly in the blue and red regions of the spectrum. This results in green light being poorly absorbed and utilized for photosynthesis in plants.
Can you tell from these absorption spectra whether red light is effective in driving photosynthesis?
No, absorption spectra provide information on the wavelengths of light that are absorbed by a pigment, but they do not inherently indicate the effectiveness of that light in driving photosynthesis. Red light is typically absorbed by chlorophyll, making it effective in photosynthesis, but further experiments like action spectra or photosynthetic rate measurements are needed to confirm its effectiveness.
What kind of light drives photosynthesis?
Plants primarily use visible light, with red and blue wavelengths being the most effective for driving photosynthesis. Green light is less efficient because it is reflected by chlorophyll.
Engelmann's experiment determined which wavelengths of light are most effective at causing photosynthesis In other words Engelmann measured?
Engelmann's experiment measured the rate of oxygen production by algae exposed to different wavelengths of light to determine which wavelengths are most effective at driving photosynthesis. He found that red and blue light were the most effective, with peaks in their absorption spectra correlating with peak photosynthetic activity.
Engelmann's investigation to determine the effective wavelengths of light in photosynthesis depended on a photosynthetic alga's?
response to varying light intensities. By measuring the rate of oxygen production in the alga under different colors of light, Engelmann was able to determine that red and blue light were the most effective in driving photosynthesis. This led to the conclusion that chlorophyll absorbs light most efficiently in these two regions of the spectrum.
What wavelength of light is the least effective in driving photosynthesis?
Green light is the least effective in driving photosynthesis because chlorophyll pigments absorb more strongly in the blue and red regions of the spectrum. This results in green light being poorly absorbed and utilized for photosynthesis in plants.
What color is the wave length of light used by chloroplast?
The wavelength of light absorbed by chloroplasts is primarily in the blue and red regions of the spectrum. These wavelengths are most effective for driving the process of photosynthesis.
Can you tell from these absorption spectra whether red light is effective in driving photosynthesis?
No, absorption spectra provide information on the wavelengths of light that are absorbed by a pigment, but they do not inherently indicate the effectiveness of that light in driving photosynthesis. Red light is typically absorbed by chlorophyll, making it effective in photosynthesis, but further experiments like action spectra or photosynthetic rate measurements are needed to confirm its effectiveness.
Why are violet-to-blue and red photons the most effective at driving photosynthesis?
Red light has the longest wavelength and the lowest energy. The chlorophyll molecules of chloroplasts absorb the red light the best because of the longer wavelength.
What kind of light drives photosynthesis?
Plants primarily use visible light, with red and blue wavelengths being the most effective for driving photosynthesis. Green light is less efficient because it is reflected by chlorophyll.
Is light with long wavelengths good for photosynthesis?
No. Unless the wavelength of the light is sufficient to excite the reaction, no amount of longer wavelength light will do anything except add to local heating.
Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis Why are they different?
The absorption spectrum shows which wave lengths are absorbed in each individual type of chlorophyll. The action spectrum shows which wavelengths of light are most effective for photosynthesis.
Engelmann's experiment determined which wavelengths of light are most effective at causing photosynthesis In other words Engelmann measured?
Engelmann's experiment measured the rate of oxygen production by algae exposed to different wavelengths of light to determine which wavelengths are most effective at driving photosynthesis. He found that red and blue light were the most effective, with peaks in their absorption spectra correlating with peak photosynthetic activity.
What color produces the lowest rate of photosynthesis?
Green light produces the lowest rate of photosynthesis because chlorophyll, the main pigment responsible for photosynthesis, absorbs red and blue light more efficiently than green light. This results in green light being less effective in driving the photosynthetic process.

What wavelength of colors do plants use for photosynthesis what color is reflect back to your eyes from a leaf?
Plants primarily use red and blue wavelengths for photosynthesis, as these are most effective for driving the process. This leaves behind green wavelengths, which are reflected back to our eyes and is why most leaves appear green to us.
What colours of light are most effective in the photosynthesis process?
