The Hydrogen Hyperfine structures gives the energy =
5.9*10\textsuperscript{-6} ev or 9.44 * 10\textsuperscript{-25} J

\(\nu\) = Frequency which we get with the equation
as\(\)\(1.4204696127\ Ghz\)
\end{quote}

\(\nu\  = \ V/\lambda\)

\(\)\(\lambda\  = \ V/\nu\)

\begin{quote}
Where V is the velocity of the wave which we consider to be the speed of
light = \(\ \ \ \ 3*\ 10^{8}ms^{- 1}\)

The $\lambda $is the wavelength of the wave which comes as 21.398 cm.
