Question

for the emission spectrum of Be3+, calculate the lowest wavenumber νˉ (in inverse meters) of light produced by electron transitions between n=2, n=3, and n=4.

An electronic transition occurs between two energy levels. Why have you listed three?

For Be3+, you can use the Rydberg formaula for energy levels, with Z = 4. The nuclear charge is +4e, and there is one orbiting electron

Perhaps what they want is the wave number for the transitions 3->2, 4->3 and 5->4.

These will be 16 times the corresponding transitions for hydrogen

Hello drwls,
could you be more specific about the forumla and how we can solve this problem ?

Hi DRWLS, please be bound by MIT EDX honor code or else you will cause trouble for everyone.

Thank you for your kind corporation.
