The hydrogen atomic emission spectrum includes a UV line with a wavelength of 92.3 nm.

Is this line associated with a transition between different excited states or between an excited state and the ground state?

What is the value of n1 of this transition?

What is the wavelength of the longest - wavelength photon that a ground-state hydrogen can absorb?

To answer the first question we can say that that line is associated with a transtition between an excited state and the ground state. We can explain this transitions in the Lyman series, which appear in the UV region of the spectrum and all terminate at the ground electronic state of the hydrogen atom. Now for the second question I have always known that the value of n1 of this transition is 1. And the wavelenght of the longest wavelenght photon that a ground state hydrogen can absorb is 121.5 nm
