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.
What else can I help you with?
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.
How does the wavelength of light affect the process of photosynthesis?
The wavelength of light affects photosynthesis by determining the amount of energy available for the process. Different wavelengths of light provide different amounts of energy, with red and blue light being most effective for photosynthesis. This energy is used by plants to convert carbon dioxide and water into glucose and oxygen.
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 is the significance of the chlorophyll optimum wavelength in relation to photosynthesis?
The chlorophyll optimum wavelength is important for photosynthesis because it is the specific range of light wavelengths that chlorophyll molecules absorb most efficiently. This allows plants to capture and convert light energy into chemical energy more effectively, ultimately driving the process of photosynthesis.
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.
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 is the significance of the wavelength 680 nm in the context of photosynthesis?
The significance of the wavelength 680 nm in photosynthesis is that it corresponds to the peak absorption of light by chlorophyll a, the primary pigment responsible for capturing light energy during the light-dependent reactions of photosynthesis. This specific wavelength is optimal for driving the process of photosynthesis and converting light energy into chemical energy.
What color is the wave length of light used by chloroplast?
Main pigment is chlorophyll.They are gree in color.

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.
How does the color of light impact the process of photosynthesis?
The color of light affects photosynthesis by influencing the rate at which plants can convert light energy into chemical energy. Different pigments in plants absorb different colors of light, with chlorophyll primarily absorbing red and blue light for photosynthesis. Other colors of light are less effective in driving the process.
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.
Does the type of light affect photosynthesis?
Yes, the type of light does affect photosynthesis. Different wavelengths of light can impact the rate of photosynthesis in plants. Blue and red light are most effective for photosynthesis, while green light is less effective because it is reflected rather than absorbed by plants.
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.
