According to the bohr model "The lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.
By explaining that electrons move in fixed orbitals (shells) and not anywhere in between, Bohr theory amended the atomic structure model.
He also showed that each orbit (shell) has a fixed energy. Bohr refined Rutherford's model of the atom's nucleus to include electrons and their varying energy levels.
According to Rydberg formula
1/λ = R [1/ni² - 1/nf²]
λ = wavelength
R = Rydberg constant
ni & nf are integers or principal quantum numbers where nf > ni
So if we want wavelength(λ) to be shortest, then 1/nf should be zero.
In this way , it depends on nf and not on ni
That's why the lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.

Given:
Volume of each of the solutions = 100 mL of each
Concentration of HCl = 0.10 M
Concentration of HNO3 = 0.10 M
Concentration of NaOH = 0.10 M
If all are mixed in one solution, the pH will surely be low since there are two acids mixed with one base. The pH range should be 1 - 5. <span />
Saturation, this is where all the octets are filled with hydrogens
3.41 is the pH value of a sample that has ten times fewer hydronium ions than an equal volume of a vinegar sample with a pH value of 2.4.
Explanation:
pH of the first sample of acetic acid = 2.4
to know the [H+] concentration in the acetic acid solution, the equation used is:
pH = -log [H+]
[H+] = 
[H+] = 
[H+] = 3.98 X 
M
The concentration of H+ ion in first case is 3.98 X M, the second sample has ten times less hydronium ion so concentration of first case is divided by 10.
3.98 x 
M
Now pH of the sample having 10 times fewer ions of acetic acid:
pH = -log [H+]
putting the values in the above equation:
pH = -log [3.98 x M]
pH = 3.41
If solution has ten times less hydronium ion the pH will change to 3.41.
