If there is a star shining through the gas then some of the starlight will be absorbed by the gas to deliver spectral lines of the "stuff" making up the gas.
Neptune's atmosphere is made up of hydrogen, helium and methane. The methane in Neptune's atmosphere absorbs the red light spectrum from the sun and reflects the blue light into space. This is why Neptune appears to be blue. The atmosphere of Uranus is composed primarily of hydrogen and helium, with a small amount of methane and traces of ammonia. Uranus gets its blue-green color from methane gas also. Sunlight is reflected from Uranus' cloud tops, which are under the layer of methane gas. As the reflected sunlight passes back through this layer, the methane gas absorbs the red spectrum of the light, allowing the blue spectrum to pass through, resulting in the blue-green color that we see.
Its not. You can't see ultraviolet. (it lies just above the visible spectrum.)
In weatherwhat is used to see cloud patterns and movements?
A rain cloud is usually a "nimbus" cloud such as the nimbostratus and cumulonimbus (thunderstorm) clouds.
The three basic types of spectra—continuous, absorption, and emission—are produced under different conditions. A continuous spectrum occurs when a solid, liquid, or densely packed gas is heated, emitting light across a wide range of wavelengths. An absorption spectrum appears when light from a continuous source passes through a cooler, rarer gas, which absorbs specific wavelengths, creating dark lines. An emission spectrum is generated when a gas is heated or energized, causing it to emit light at specific wavelengths characteristic of the elements present.
The actual presence of the gas cloud's contents will absorb certain wavelengths of Light, preventing the passage of certain photons through the cloud, that results in that Light not reaching us - producing a blank line in the observed spectrum.
Look and see where it is leaking from.
To test a pressurerized gas line apply soapy water to all connections. You will see bubbles appear if there are leaks. I see plumbers do this at the houses I work on.
It's a line spectrum because of the quantization of energy- meaning you only see energy with levels n=1,2,3.... One would never see the energy level n=2.8 for instance- that would be the case if it were continuous rather than a line spectrum.
Certainly; you can see the light that it gives off.
We can see the visible spectrum of light, which ranges from violet to red. This spectrum includes all the colors of the rainbow.
Check the gas line disconect the line going to the carb and blow on it or let it run some out of the line to see if its getting gas.

No, the solution is the air that you can see through before the cloud forms when you see the cloud the water has come out of solution.
"Emission Spectrum" can mean a number of things... Many objects emit light and they all have an emission spectrum, that is a set of wavelengths of light that they give out. The emission spectrum for an L.E.D. bulb for instance is pretty narrow, just one visible colour. The emission spectrum of a star is very wide, encompassing non-visible light as well. It is probably these stellar emission spectra you are referring to, so I'll go on from that assumption. The fusion processes within a star (at most levels from core to surface, but mostly in the core) create most of a spectrum, but some of this light is absorbed by the outermost layers. That is why we see gaps, and molecules of certain types absorb certain parts of the spectrum, so we use the spectrum to determine composition. We also see spectra from diffuse bodies like nebulae. These are, broadly, of 2 types, emission and absorption. Absorption spectra occur when we observe a known star through the cloud, and extra lines missing beyond what we expect of the star will be emblematic of the constituents of the cloud. Emission spectra from clouds can also occur, that is when the light falling on them is not aligned with us, what we see is several narrow bands of light, which has been absorbed and re-emitted by the cloud.
Its not. You can't see ultraviolet. (it lies just above the visible spectrum.)
Dispersion, the separation of visible light into a spectrum, may be accomplished by means of a prism or a diffraction grating. Each different wavelength or frequency of visible light corresponds to a different color, so that the spectrum appears as a band of colors ranging from violet at the short-wavelength (high-frequency) end of the spectrum through indigo, blue, green, yellow, and orange, to red at the long-wavelength (low-frequency) end of the spectrum. In addition to visible light, other types of electromagnetic radiation may be spread into a spectrum according to frequency or wavelength. The spectrum formed from white light contains all colors, or frequencies, and is known as a continuous spectrum. Continuous spectra are produced by all incandescent solids and liquids and by gases under high pressure. A gas under low pressure does not produce a continuous spectrum but instead produces a line spectrum, i.e., one composed of individual lines at specific frequencies characteristic of the gas, rather than a continuous band of all frequencies. If the gas is made incandescent by heat or an electric discharge, the resulting spectrum is a bright-line, or emission, spectrum, consisting of a series of bright lines against a dark background. A dark-line, or absorption, spectrum is the reverse of a bright-line spectrum; it is produced when white light containing all frequencies passes through a gas not hot enough to be incandescent. It consists of a series of dark lines superimposed on a continuous spectrum, each line corresponding to a frequency where a bright line would appear if the gas were incandescent. The Fraunhofer lines appearing in the spectrum of the sun are an example of a dark-line spectrum; they are caused by the absorption of certain frequencies of light by the cooler, outer layers of the solar atmosphere. Line spectra of either type are useful in chemical analysis, since they reveal the presence of particular elements. The instrument used for studying line spectra is the spectroscope.
