Ответ:
the final state of the hydrogen atom = 3
Explanation:
From the given information;
Let first calculate the amount of energy by the ground state atom during the atoms absorbs photon light by using the formula:
where;
h = planck's constant =![6.626*10^{-34 }\ \ Js](/tpl/images/0699/3893/c357b.png)
c = speed of light =![3.0*10^8 \ \ m/s](/tpl/images/0699/3893/7cac1.png)
λ = wavelength = 92.57 nm = 92.57 × 10⁻⁹ m
The energy emitted by the hydrogen atom is calculated by using the same formula from above ; but here , the wavelength λ = 954.3 nm = 954.3 × 10⁻⁹ m
The change in the energy absorbed is:
The final state of the atom can be determined by using the relation:
where;
Thus; the final state of the hydrogen atom = 3
