A hydrogen atom undergoes a transition from the state n=3 to n=2 and then another transition from the state n=2 to n=1.

9. A hydrogen atom undergoes a transition from the state n=3 to n=2 and then another transition from the state n=2 to n=1. Two photons are created due to these processes. Which photon has the higher frequency? 10. A particle's momentum is measured with great accuracy. What can be said about its position

Spectroscopic Notation

Could you please answer the attached question regarding spectroscopic notation in atomic physics. Also, please give an explanation. Thank you.

If you body is emitting infrared radiation of wavelength 9.4 x 10^(-6)m, what is the energy of the released photons?

If you body is emitting infrared radiation of wavelength 9.4 x 10^(-6)m, what is the energy of the released photons? A hydrogen atom initially in the n =3 level emits a photon and ends up in the ground state. a) What is the energy of the emitted photon? b) If this atom then absorbs a second photon and returns to the n =3,state what must the energy of this photon be? The amount of carbon -14 in an ancient wooden bowl is found to be one-half that in a new piece of wood. How old is the bowl?
