There are only certain wavelengths that can be accepted and absorbed by chlorophyll molecules. The rest are instead reflected - the colors that you can see. Without those wavelengths, you do not have photosynthesis.

Do some wavelengths of light cause more newspaper yellowing than others?
the major cause of newspaper yellowing is leftover processing acids in the pulp used to make the paper, not light.
What do light waves of greater frequency have?
The meaning of a high frequency wave is a shorter wavelength.For electromagnetic waves in general (including light):* At greater frequencies, you get shorter wavelengths.* At greater frequencies, you get more energy per photon.
Why different colors appeared by different material?
White light is a mixture of different colors. Different materials have different surface properties; as a result, one material may reflect a larger percentage of red light, and a smaller percentage of other colors, such as blue or green light - thus, it will appear red. Another material may reflect more green light than other colors, so it will appear more green.
Do you measure photons energy with wavelengths?
you see how close the wavelengths are-- the closer, the more powerful it is. Here are the wavelengths- from least powerful to most powerful: Radiowaves, Microwaves, Infared Waves, Visable Light, Ultraviolet, X-rays, and Gamma rays.
What does an spectroscopy measure?
It measures the relative amounts of light of different wavelengths absorbed and transmitted by a pigment solution.
Why are Chlorophyll b and the carotenoids important as receptors of light energy?
These pigments are able to absorb more wavelengths of light (and thus more energy) than chlorophyllaalone can absorb. As part of light-harvesting complexes in photosystems, they broaden the range of light that can be used in the light reactions.
What affects light with short wavelengths more than light with long wavelengths?
Scattering of light
What bends more light waves with short wavelengths or light waves with long wavelenths?
Light waves with long wavelengths
Do some wavelengths of light cause more newspaper yellowing than others?
the major cause of newspaper yellowing is leftover processing acids in the pulp used to make the paper, not light.
What type of light is scattered the most in your atmosphere?
Here on earth it is violet wavelengths that scatter the most, however the earth's sun emits more blue light than violet so blue wavelengths are scattered more frequently than violet wavelengths.
Why are short wavelengths of EM radiation less common then medium wavelengths?
Shorter wavelengths, like gamma rays and X-rays, require more energy to produce than longer wavelengths like visual light.
Are shorter wavelengths more affected by a prism or water droplets than longer wavelengths?
False. A prism separates the colors of sunlight into a spectrum because each wavelength of light has its own index of refraction, not because wavelengths are affected more or less by the prism.
Why are objects coloured?
It is because they reflect certain wavelengths (colors) of light more readily than others. White light contains all wavelengths of light. You can see this by passing the light through a prism or by observing a rainbow. Now, if you have an object such as an orange and shine white light on it. The red and yellow will be reflected and the other colors will be absorbed. Thus, we see an orange object. Now, if you shined pure blue light on the orange it would look black, because there would be no red or yellow to reflect.
Examples of tyndall effect?
The scattering of light by particles in the atmospere making the sky appear blue as blue wavelengths are scattered more strongly compared to red wavelengths.
What portion of the electromagnetic spectrum is used in optical fiber communication?
Fiber optic cables use wavelengths of visible light to transmit data. (Some use infrared as well.) They use red and above with the higher wavelengths being of higher speed and quality. The higher the wavelengths of light used, the more expensive the equipment is.
How does changing wavelength in the activity vary the light that you see?
The human eye is sensitive to a range of wavelengths within the electromagnetic spectrum, and different wavelengths correspond to different colors. The visible spectrum spans from shorter wavelengths (associated with violet and blue colors) to longer wavelengths (associated with red and beyond). Here's how changing the wavelength can affect the light you see: Color Perception: Shorter Wavelengths (Blue/Violet): Shorter wavelengths are associated with blue and violet colors. As the wavelength decreases, the light appears more towards the blue end of the spectrum. Medium Wavelengths (Green/Yellow): Medium wavelengths are associated with green and yellow colors. Longer Wavelengths (Orange/Red): Longer wavelengths are associated with orange and red colors. As the wavelength increases, the light appears more towards the red end of the spectrum. Intensity and Brightness: Generally, the perception of brightness is more strongly influenced by intensity rather than wavelength. However, changes in wavelength can affect the overall color appearance, and our eyes may perceive certain colors as more or less intense. Color Mixing: Combining light of different wavelengths can result in color mixing. For example, combining red and blue light can produce magenta, while combining red and green light can produce yellow. Interference and Diffraction: Changes in wavelength can also be associated with optical phenomena such as interference and diffraction. These effects can result in patterns of colored fringes or bands, particularly when light interacts with fine structures or passes through narrow openings. Scattering: Shorter wavelengths of light (blue and violet) tend to scatter more than longer wavelengths (red and orange). This is why the sky appears blue during the day; the shorter blue wavelengths are scattered in all directions by the gases and particles in the Earth's atmosphere. Absorption:
An object that reflects all colors appears to be what color?
White.==================2nd opinion:An object that reflects all colors appears to be the same coloras the light with which it's being illuminated, whatever that is.3rd answer.The second opinion shows a misunderstanding of light. some wavelengths are absorbed more than others, which leaves the reflected wavelengths we see.As the question specified 'all colours' then the correct answer is white.
