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 else can I help you with?
Is the sun dark matter?
No, the sun is not dark matter. Dark matter is a mysterious form of matter that does not emit, absorb, or reflect light. The sun, on the other hand, is a star that emits light and heat due to nuclear reactions happening at its core.
How do you distinguish colour and brightness?
Color refers to the perceived hue of an object or light source, determined by the wavelengths of light it reflects or emits. Brightness, on the other hand, refers to the intensity of light emitted or reflected by an object, regardless of its color. Color can be affected by factors like pigmentation, while brightness is influenced by the amount of light hitting a surface.
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 light wave lengths are reflected in chlorophyll?
Green light is reflected. Red and blue light are absorbed.
What light can be detected by the eye?
The human eye can detect visible light, which is part of the electromagnetic spectrum that ranges from violet (shorter wavelengths) to red (longer wavelengths). It cannot see light from other parts of the spectrum, such as ultraviolet or infrared light.
How do the emission spectra for hydrogen and helium differ from each other?
The emission spectra for hydrogen and helium differ in the specific wavelengths of light they emit. Hydrogen emits light in distinct lines corresponding to transitions of its electrons between energy levels, while helium emits a continuous spectrum of light.
What term describes the purity of a wavelength?
Monochromaticity refers to the purity of a single wavelength in light or other electromagnetic radiation. A monochromatic source emits light at a single specific wavelength without any other wavelengths present.
How do wavelengths absorbed by cans differ from wavelengths radiated?
Wavelengths absorbed by cans correspond to the specific frequencies of light or energy that the material of the can is able to capture and convert into heat. On the other hand, wavelengths radiated by cans relate to the frequencies of light or energy that the material emits as heat due to its temperature. The absorbed wavelengths contribute to the internal energy of the can, while the radiated wavelengths represent the release of that energy in the form of heat.
How does a spectrofluorometer work?
A spectrofluorometer works by emitting light of a specific wavelength onto a sample, which then absorbs and re-emits light at longer wavelengths (fluorescence). The instrument detects this fluorescent light and measures its intensity at different wavelengths. By analyzing the emitted light, the spectrofluorometer can provide information about the sample's molecular structure, concentration, and other properties.
Is the sun dark matter?
No, the sun is not dark matter. Dark matter is a mysterious form of matter that does not emit, absorb, or reflect light. The sun, on the other hand, is a star that emits light and heat due to nuclear reactions happening at its core.
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.
How is white light created and what are the components involved in its production?
White light is created by combining all the colors of the visible spectrum together. The components involved in its production include a light source, such as the sun or a light bulb, that emits a broad range of wavelengths. These wavelengths are then refracted or reflected by a prism or other optical device to separate them into the different colors, which are then recombined to form white light.
Light from the sun is what color?
White. Although the sun emits light in a variety of wavelengths, our atmosphere scatters shorter wavelengths more effectively, resulting in the sky appearing blue. When the sun is lower in the sky, its light passes through more atmosphere, causing shorter wavelengths to scatter away and leaving longer wavelengths like red, orange, and yellow to create the colors we see during sunrise and sunset.
How can light waves move from empty space into matter made up of different gases?
Light waves can move from empty space into matter, such as gases, through a process called absorption. When light interacts with matter, the atoms and molecules in the gases absorb specific wavelengths of light. This absorption causes the light waves to lose energy and transfer into the matter as heat or other forms of energy.
What colour will the lamp appear if you look at it though a green filter?
When you look at a lamp through a green filter, the lamp will appear green if it emits green light or reflects green wavelengths. If the lamp emits other colors, such as red or blue, those colors will be filtered out, making the lamp appear dark or black, as the green filter only allows green wavelengths to pass through. Thus, the perceived color depends on the light source's color and the filter's properties.
Does a flame have a shadow?
No, a flame does not have a shadow because it emits light and does not block light from other sources.
Red light and white light reflect?
All of the electromagnetic spectrum can be reflected. White light is a combination of all colors. They all reflect, red is among them.
