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.

What conditions lead you to see an absorption line spectrum from a cloud of gas in interstellar space?

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.


How do you tell if a gas leak is from the fuel line or gas tank?

Look and see where it is leaking from.


How do you do pressure test on gas line?

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.


Why is the emission spectrum of hydrogen a line spectrum and not a continuous spectrum?

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.


What spectrum can we see?

We can see the visible spectrum of light, which ranges from violet to red. This spectrum includes all the colors of the rainbow.


Does the flame of the gas stove give light of visible wavelength?

Certainly; you can see the light that it gives off.


What is wrong with a 4 stroke dirt bike that shuts off?

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.


Is a cloud a solution?

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.


What gas gives Uranus a bluish color?

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.


Can we see most of the light in the spectrum?

No. We can only see visible light, which is only a small portion of the electromagnetic spectrum.


Why is the part of the electromagnetic spectrum you can see called ultraviolet light?

Its not. You can't see ultraviolet. (it lies just above the visible spectrum.)


Is it true or false that you can see most of the light in the spectrum?

False. People can only see the Visible Light spectrum, which is only a small section of the overall light spectrum.
