No.
Dark matter emits no EM radiation that we can detect, and we can detect light from galaxies outside the Milky Way over 17 orders of magnitude. Specifically, from radio waves as long as 10 meters to gamma rays of over 1 GeV in energy. Since there is far more gravitational interaction between dark matter and baryonic matter (ie, the stuff we understand) than that occuring between baryons, then it would be truly bizarre that we could not detect any EM radiation coming from dark matter. If it were emitting EM radiation, then we should see more of it than we can see coming from baryonic matter. But we don't see anything. So either dark matter has no EM interaction (ie, no EM radiation) or its EM interaction is so weak and different than that for baryons.

What color does not absorb all wavelength of light?
Black is the only color that does absorb all wavelengths of light.White is the color that reflects all wavelengths of light.All other colors absorb only certain wavelengths of light and reflect the rest.
What emits light and what reflects light?
stars,metiorite and the sun emit light,comites do both. other than that the moon and the planets reflect light
What is the fastest visible light wavelength?
If you're talking about how long it takes light to get from here to there ... all wavelengths of light, as well as all wavelengths of every other example of electromagnetic radiation, all travel at the same speed.
Is visible light longer or shorter then rays?
Visible light is made of rays. There are rays with wavelengths that are shorter than visible light and other with longer wavelength.
What physical phenomenon is causing each dye to absorb light of one or more colors and transmit light of other colors?
In a spectrometer, each dye will absorb light of certain colors and transmit light of other colors because of the nature of the atoms of the object and the frequency of the light. If the frequency of the light is the same as the frequency that the electrons in the atoms are vibrating, then the light will be absorbed and transferred into vibrational motion.
Which is hot a blue star or a red star and why?
All stars are hot. Blue stars are the hottest. The hotter a star is, the shorter the wavelength of light it emits. Blue light has a shorter wavelengths than most other colors.
What is the difference between UV lamps and IR lamps?
One emits light in the ultra-violet range, and the other emits light in the infrared range.
What is the color of an object is?
The color of an object are defined by the wavelengths of visible light that the object reflects. This reflected light is picked up by our eyes and interpreted as color. The other wavelengths of light are absored.
What color does not absorb all wavelength of light?
Black is the only color that does absorb all wavelengths of light.White is the color that reflects all wavelengths of light.All other colors absorb only certain wavelengths of light and reflect the rest.
Why do objects appear the color they are?
It's a matter of selective absorption and reflection of the varying wavelengths of light. Our eyes and brain work together to interpret the different wavelengths of light as different colors. White light is composed of all possible wavelengths of visible light, and sunlight is very nearly white. Characteristics of various surfaces cause them to reflect or absorb certain wavelengths. The ones that are reflected to our eyes are what determine the color we perceive. To cite just a single example, if a ball is red, it reflects red light and absorbs the other colors. That's why it appears red. The issue is slightly different for a source of light, and the answer speaks to all other things we see and the colors they appear to have.
If white light goes into a material and only blue light comes out the other wavelengths have been?
absorbed
What does an electromagnetic refer to?
A range of wavelengths of light that increases from one end to the other
Why does chlorophyll look green?
It absorbs all other wavelengths of visible light.
Why are objects the color that they are?
Visual perception is a result of light being detected by your retina at the back of your eye. Light of different wavelengths determines colour. Objects that are a specific colour absorb light of certain wavelengths and reflect light at other wavelengths. So if an object is green that is because it is absorbing the red and blue light and reflecting green.
What determine the color of an object?
Light comes in many different "wavelengths". The wavelength of a beam of light determines its color.White light contains light of all different wavelengths, but objects can reflect of absorb different wavelengths.The light that an object reflects determines its color.In other words, an object that looks red must be absorbing all wavelengths of light except red.
