Why do electrons in hydrogen atoms emit infrared light when they make transitions to the n=3 energy level and uv light when they make transitions to the n=1 level?
Does this have to do with wavelengths?

  • Physics -

    yes
    The larger the energy loss in the transition, the higher the energy of the photon emitted.
    The energy of a photon is proportional to its frequency.
    therefore a transition from a higher level to n=1 will have a higher frequency (shorter wavelength) than a transition to the n=3 level
    UV is higher frequency (shorter wave), infrared is lower frequency (longer wave)

    Wow, Thanks, that helped a lot!
