According to the bohr model of the atom, which electron transition would correspond to the shortest wavelength line in the visible emission spectra for hydrogen?

Explanation:

According to Bohr's model, electrons are travelled in defined circular orbit around the nucleus. The orbits of different energy level is labelled by quantum numbers (n). Electrons can jump different energy levels, from higher to lower energy level by releasing energy.

In the visible emission spectrum of hydrogen, there are mainly five series which we are studied in regular. Series are: Lyman series(n=1), Balmer series(n=2), Paschen series(n=3), Bracket series(n=4), Pfund series(n=5).

Wavelength is inversely proportional to the quantum number(n). So, we can conclude that greater the value of n shortest the wavelength. According to above spectral series Pfund series(n=5) have shortest wavelength.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
