Question

Calculate the wavelength of a photon emitted when the electron in a Li2+ ion relaxes from the n=8 energy level to the n=4 energy level. (Use Bohr's model of the atom.)

Answer #1

If the wavelength of light emitted when an electron relaxes from
n = 3 level is 102.6 nm, to what level did the electron relax
to?

Calculate the energy of the emitted photon as well as the
wavelength and frequency of electromagnetic radiation emitted from
the hydrogen atom when the electron undergoes the transition from n
= 5 to n = 1. In what region of the spectrum does this line
occur?

What is the wavelength of light (in m) emitted by a hydrogen
atom when an electron relaxes from the 5 energy level to the 3
energy level?

What is the wavelength of the photon emitted as the electron in
the hydrogen atom transitions from the 3rd to 2nd level? What is
the frequency of the photon and what is the energy carried by the
photon?
got -6606 A for the first one and I'm not sure if I'm doing it
right
