No. Any harmful radioctive substances in the light have already been absorbed by the atmosphere or reacted with elements in it. This is all due to wavelength etc. Check out http://hypertextbook.com/facts/2002/PavelBorodulin.shtml No. Any harmful radioctive substances in the light have already been absorbed by the atmosphere or reacted with elements in it.

Visible light waves, or the stream of photons with frequencies within the band
allocated to human visual applications, as well as their spurious products and
inadequately suppressed harmonics (the photons' that is, not the humans'), can
indeed often prove harmful, typically and primarily with regard to their potential
emotional consequences. It's impossible to over-estimate the chance possibility
of an individual's inadvertent exposure to scenes that anger, annoy, befuddle,
confuse, corrupt, erupt, disrupt, disappoint, disorient, depress, oppress, irritate,
terrify, titillate, or stimulate a thousand other outrageous and unfortunate slings
and arrows that flesh is heir to. And, considering the element of surprise, it is
unlikely that one could, simply by opposing, end them. As the danger is primarily
emotional, so is the solution: The conscious decision taken by every man-jack
among us, in his heart, that his synapses and receptors were not created for
moments when there is no stress, but that they are for such moments as these,
when body and soul rise up in mutiny against their rigour, that he consider the
alternative, and resolve that he just won't let things like that bother him.
Gamma Rays which have shorter wavelengths than the other types of waves on the electro magnetic spectrum
UV-B
Light waves with long 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.
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.
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:
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.
The shorter electromagnetic wavelengths are the more harmful. Shortwave ultraviolet is more harmful than long wave ultraviolet light. With even shorter wavelengths are gamma rays and x-rays which can cause genetic mutations and cell damage leading to death.
Scattering of light
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.
Light waves with long wavelengths
the major cause of newspaper yellowing is leftover processing acids in the pulp used to make the paper, not light.
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.
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.
Yes, but some viruses are more harmful than others.
Shorter wavelengths, like gamma rays and X-rays, require more energy to produce than longer wavelengths like visual light.
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.
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.
