Marks: +1, -0

An atom has energy levels En=−‌

where n is an integer and A is a constant. Among the spectral lines that atom can absorb at room temperature are two adjacent lines with wavelengths 97.5nm and 102.8nm. Select the correct alternative(s)

A=54.4eV
A=13.6eV
The wavelength 97.5nm corresponds to transition from n=1 to n=3
The wavelength 102.8nm corresponds to transition from n=3 to n=4
