hi guys, having a bit of trouble answering this physics question. Wondering if any of the experts can help me out.(adsbygoogle = window.adsbygoogle || []).push({});

Can the electromagnetic radiation produced by a hot gas of hydrogen atoms be exactly of one frequency?

They say also that the atoms make a transition from state n=2 to n=1 and that all atoms are moving.

not sure about this one. From what I saw in tutorial hot gases show several frequencies. Am I thinking of the right thing, the spectra that shows from the slit experiments with all the vertical spectrum lines.

hope someone can help

oh, a similar question involving state transitions

A hydrogen atom undergoes a transition from the state n=3 to n=2 and then another transition from n=2 to n=1. Two photons are created due to these processes. Which photon has the higher frequency?

I have thought about this one all night, and can't understand it. They say two photons are created, I'm not sure if they mean at once, or one from state n=3 to n=2 and one from n=2 to n=1.

any thoughts?

thanks
