Why is chlorophyll a also called chlorophyll 680?
Chlorophyll a is also called chlorophyll 680 due to its peak absorption of light at a wavelength of 680 nm. This specific absorption wavelength corresponds to the optimal energy level needed for chlorophyll a to carry out the process of photosynthesis efficiently.
What percentage of green light does chlorophyll reflect?
Chlorophyll reflects around 5-10% of green light and absorbs the rest for photosynthesis. This is why chlorophyll appears green to our eyes.
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.
Light of the green wavelengths is commonly absorbed by which accessory pigment?
Carotenoids and chlorophyll b absorb some of the energy in the green wavelength.
Do plants absorb or reflect green light?
YES. Plants absorb AND reflect green light. Leaves are green due to a compound called chlorophyll. The light absorbed by chlorophyll is used to power photosynthesis, the conversion of light energy into chemical energy. On a relative basis, chlorophyll absorbs more blue and red light, compared to green light; and therefore reflects less red and blue light. As a result, there is more green light than red or blue light reflected, so the chlorophyll containing part of the plant appears green. It is commonly thought that chlorophyll does not absorb green light, but that is a fallacy. A dark green leaf can absorb 90% of the green light impinging on it. In contrast, 95% of the red and blue light may be absorbed.
Which light wavelength and color is reflected by the pigment chlorophyll?
green
Wavelength of light would you expect to be reflected or transmitted by chlorophyll a?
green
What color light does the chlorophyll in plants reflect best?
green
What percent of light of this color does chlorophyll reflect?
Chlorophyll reflects between 5-10% of green light and absorbs the rest for photosynthesis.
Does plane mirror reflect rays of all wavelength?
Yes, plane mirrors reflect all wavelengths of light in the same way. The reflection of light off a mirror does not depend on the specific wavelength of light.
Why is chlorophyll a also called chlorophyll 680?
Chlorophyll a is also called chlorophyll 680 due to its peak absorption of light at a wavelength of 680 nm. This specific absorption wavelength corresponds to the optimal energy level needed for chlorophyll a to carry out the process of photosynthesis efficiently.
What is the optimum wavelength of light absorbed by chlorophyll and why?
The optimum wavelength of chlorophyll is 430nm (in a light spectrum of 380nm-750nm going in 10 incements) We did a lab and it required us to determine the optimum wavelength of chlorophyll by testing the absorbance of light in 10nm increments from 380nm-750nm. Optimum wavelength is the wavelength of light that is absorbed best by a substance. So when we tested all the wavelngths 380-750 in 10 increments (380,390,400,410,420....) 430 had the highest absorbance. we used a Spec 20 machine to find the absorbance.

What color does chlorophyllr reflect?
Chlorophyll reflects green light. That is why plants look green!
Is a plant pigment that absorbs most wavelength of light?
The ozone acts like a sunblock for the earth, so it absorbs most of the ultraviolet radiation.
What colors does chlorophyll reflect?
In most plants, the predominant type of chlorophyll reflects green light - this is why most plants appear to be green to our eyes. However, there are other types of chlorophyll that reflect red, orange and yellow light - you see these in leaves that are shed in the fall from deciduous trees in temperate forests.
