Assume that there are a series of emissions for the hydrogen atom in which n(subscript f) = 2, find the electromagnetic spectrum in which these emissions are observed.

Question

aaronq · Answer

use the rydberg equation to find the wavelengths of light correspondent to transitions from n>2 to n=2.

       $\dfrac{1}{\lambda}=R \;(\dfrac {1}{n_f^2}-\dfrac{1}{n_i^2})\      \;\;;\;\;\;\;\;  where,\;R=\dfrac{m_ee^4}{(4\pi)^3\epsilon_0^2\hbar^3c }\approx1.097*10^7 m^{-1}$

Hi, thanks for the answer, what should I plug in for n1 and n2?

aaronq · Answer

Emission implies that $n_i>n_f$, and in the question it's telling you that $n_f$=2, so $n_i$>2.

aaronq · Answer

the question is asking for a spectrum; in other words, a range.
