ATOMIC STRUCTURE

None

Let us consider a sample of hydrogen atoms and in each atom, the electron is excited to the energy level n. What is the maximum number of unique wavelengths this sample can emit?

I don't have the answer with me. So, please give the explanation part also, not just the answer.

why are you so confused? I have not considered repitions. I have considered only the unique wavelengths. I have taken into account all the choices an atom will have. so in a sample of atoms, all the atoms would have the same no. of choices. A single atom could emit one or more of these wavelengths depending upon the transition. but all the atoms have to choose among these. even 2 atoms may emit same wavelength. But I have not given the no. of all the wavelengths. I have given the no. of all possible wavelengths.
