ground state a total of 6 different types of photons were emitted
out of 6 photons three have wavelength less than 54 nm
determine
a initial and final excited states
​b ionization energy
​c atomic number

Your case is given with insufficient data But I can give the
steps
First calculate the Wavelengths of the photons using1λ = 1λ1 + 1λ2 + 1λ3 + 1λ4 + 1λ5 + 1λ6For the first three its given < 54 nm, so the next three should be > 54 nmBut this value is not exact value
 You should give some more details to calculatethe photons λ values
 Second from the λ value set ∆E should be calculated
 ∆E= hcλNext calculate the n1 and n2 values
 ∆E= RH z2 1n12 -1n22 Next ionisation energy = - EFor calculating atomic number either E value or λ value of the new species should be given
