We can find the energy needed to ionize the hydrogen atom.
We can find the wavelength of a spectral line.
We can find the energy change of the electron moving between two levels.
The first atomic model to adequately explain the radiation spectra of atomic hydrogen was Bohr's model of the hydrogen atom. The atomic Hydrogen model was first presented by Niels Bohr in 1913. Rutherford's model of the hydrogen atom leaves several holes, which Bohr's model of the hydrogen atom tries to fill in.
It has a particular place in history since it introduced the quantum theory, which led to the development of quantum mechanics. Bohr proposed that electrons moved in predetermined orbits or shells with defined radii around the nucleus. It was impossible for electrons to reside between any shells other than those having a radius given by the equation below.

The value of γ needed for transformation between the two frames is 2.2942.
To transform the position, time, mass from one coordinate frame to another frame which moves with a speed v relative to the first, we need to calculate the Lorentz constant γ .
This is given by,
Substitute for v and
for <em>c</em>.
The Lorentz factor needed for transforming the position and time coordinates from the given frame to the frame moving with a speed v relative to it is 2.2942
