What wavelengths of light does chlorophyll absorb the best?
The blue and the red spectrum of visible light is best absorbed by chlorophyll.http://www.ndpteachers.org/perit/Absorption%20Spectrum%20%5B2%5D.jpg
Is red best for plant growth?
Red or blue light are the wavelengths of the visible light spectrum that are most absorbed by plants.
Do plants grow taller in green light or white light?
All the colours of the rainbow have different wavelengths. For example, violet has short wavelengths, while red has long wavelengths. Visible light appears as white light because it is a mixture of all the colours. Also, chlorophyll is the principal pigment involved in photosynthesis. Chlorophyll absorbs all the different coloured wavelengths, but leaves green as the colour it reflects and as the colour we see.Therefore, white light is best to grow plants under because green light doesn't do much of anything for photosynthesis.
How does light enter the light dependant reaction?
Blue and red absorbed best. Green is not absorbed
Which best describes visible light in relation to other forms of electromagnetic radiation?
Visible light is a small region of the electromagnetic spectrum that is characterized by a specific range of wavelengths and frequencies
What chlorophyll a and b absorb?
Chlorophyll a and b absorb BLUE-VIOLET and RED wavelengths of light best.

What color reflects heat best for an outside umbrella?
White light is made up of all the different colors of light, as can be seen when it is separated into these various wavelengths using a prism. The colors that we see are the wavelengths of light that are being reflected off of the objects we are looking at. Objects that are red will reflect only red wavelengths and will absorb the other wavelengths; objects that are blue will reflect only blue wavelengths and will absorb the other wavelengths; etc. Black objects absorb all visible wavelengths of light, which is why black asphalt gets so hot in the sunlight. White objects reflect all wavelengths of light. Therefore, a white umbrella would reflect the largest amount of light. However, this does not necessarily imply that it would be the best color to use for an umbrella because what really matters is how much light is transmitted through the umbrella to reach the shade below. The more light that gets through, the less effective the umbrella is in providing you with shade. Therefore, what really matters is how opaque the umbrella is, rather than what color the umbrella is. The opaqueness will be more characteristic of what material the umbrella is made of than what color it is. The fraction of the light that is transmitted will equal all the light that strikes the umbrella that is neither reflected nor absorbed. Thus, it is best to find an umbrella which combines high reflectivity with high opaqueness (generally a thick material) in order to keep the umbrella from heating up and stop the greatest percentage of the sun's rays from reaching you.
What wavelenths of light does chlorophyll a absorb best?
430 nm
Is red best for plant growth?
Red or blue light are the wavelengths of the visible light spectrum that are most absorbed by plants.
What colors best absorb light?
dark colours with the best one for this being black.
Which parts of spectrum do carotenoids absorb best?
blue and green light
Does an object that appears to be blue absorb red light?
The best way to answer is to: Google It
What colors absorb light?
dark colours with the best one for this being black.
Which best explains the role of plant pigments in photosynthesis?
They absorb light energy.
Which is the best absorber of inferared radiation heat a dull surface or a shiny one?
A dull surface will absorb infrared best, but it needs to be dull at infrared wavelengths. Do not judge the infrared behavior by the visible performance.
