Is Mercury Blue or Silver?
Mercury appears silvery in color due to its reflective surface, which is primarily composed of metallic elements. The planet's thin atmosphere also contributes to its silvery appearance.
Is the color observed in the flame test the result of the metallic ion or the nitrate ion explain why?
Nitrate ions have no colour, while transition metal ions do. The colour in the transition metal is due to ligands (such as nitrate in this case) approaching the ion along the x, y and z axes. As the dx2-y2 and dz2 orbitals lie on these axes they will be repelled by the ligand (negative charges repel each other). The other orbitals (dxy dyz and dxz) do repel the ligand as well just to a much lesser extent. This creates an ligand field (difference of energy between the orbitals) Photons are then absorbed by the dxy dyz and dxz orbitals . The wavelength of photons absorbed will affect the colour of light seen, ie if green light is absorbed violet will be seen (in permanganate ions).
What is the colour of chlorine?
the colour of Chlorine is green.
What sort of wavelengths does infrared radiation have?
Infrared is from about 0.7 microns to maybe 100 microns or so. Visible light runs from about 0.7 (red) to 0.4 microns (purple), so anything longer than that is "infrared" which means "below red". It's a little fuzzier where infrared ends and microwaves begin. 100 microns is one possible definition. Terrestrial radiation peaks at about 10 microns, so that's definitely IR. 300 GHz is 1 mm or 1000 microns, and it's definitely microwaves. Terrahertz radiation is the current no-mans-land between microwaves and infrared, and 1 Terrahertz is 333 microns.
What colour is Ferrous oxide?
Ferrous oxide is typically a black or dark brown color.
Is the amount of heat raditation absorbed by a surface depends only on its colour?
No !
How much solar energy is absorbed and how much is reflected from the earth's surface?
At the earth's surface about 51% of incoming solar radiation is absorbed, and 4% is reflected back into space.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
Why does black absorb the most energy from the sun?
Firstly, black is not a colour - it is the absence of colour (white isn't a colour either - it is a mixture or combination of all 'colours'). We see colour when its particular wavelength is reflected of the surface of something. The wavelength(s) reflected depends on the composition of the surface. Back to black - so when we see 'black' it is because all wavelengths of light has been absorbed by that surface. Light is energy; all that energy being absorbed = heat.
Is there such thing as dark white?
The colour 'white' when all of the light is bounced of the surface on which the colour is mounted. If the colour is darkened then there will be some light being absorbed into the surface. This means that the colour is no longer 'white' more of a grey or possibly black. :)
What happens to the rays when white light strikes a coloured surface?
The waves whose frequencies belong to that colour are reflected while other frequencies are absorbed.
What is the effect of colour on radiation heat transfer?
The color of a surface affects its emissivity, which is a measure of how efficiently the surface emits thermal radiation. Dark-colored surfaces typically have higher emissivity and thus absorb and emit more radiation compared to light-colored surfaces. This can impact the rate of heat transfer through radiation between surfaces of different colors.
Why do stars change colours?
They don't actually change colour but the earth's atmosphere causes an apparent change of colour according to the time of day. And other factors like the amount of radiation emitting from the star itself.
Why is white not a colour?
Colours are made because rays of coloured light are absorbed into whatever object. With white, all coloured rays are reflected and none are absorbed. It's not a colour, it's actually the lack of any colour.
How do people see light?
the light is absorbed and the colour comes out into your eye xoxoxo
What colour of light will be absorbed first as the sunlight enters water?
Infra-red
How a spectrophotometer measure change of colour?
A spectrophotometer measures the change in color by analyzing the amount of light absorbed or transmitted by a sample at different wavelengths. It quantifies the intensity of light absorbed by the sample and then converts this data into a measurable color change. This is done by comparing the absorbance spectrum of the sample to that of a reference.
Why are orange things orange?
colour depends on how much sunlight is reflected and absorbed. White is the colour that reflects all sunlight, black is the colour that absorbs all sunlight.
