To find the wavelength emitted by a helium ion
during the transition of an electron from the second energy level to the first, we can use the Rydberg formula:
where:-
is the wavelength of the emitted light,-
is the Rydberg constant (
),-
and
are the principal quantum numbers of the lower and higher energy levels, respectively.For the transition from the second energy level (
) to the first energy level (
), we have:
Now, we can solve for
:
Substituting the value of the Rydberg constant:
Therefore, the wavelength emitted by a helium ion
during the transition of an electron from the second energy level to the first is approximately 292 nm.
