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

not sure if this is true or not. They say also that the atoms make a transition from state n=2 to n=1 and that all atoms are moving.

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?

any thoughts?

thanks
