Summary of the Blamer Lab
The main goal of the Blamer Lab was to measure the wavelength of the emitted light when you were to excite hydrogen gas to different excited states. Once you measured these wavelength's you could then calculate the Rydberg Constant, which was the goal for the experiment. I did this with the use of a hydrogen tube that was excited via the use of electricity and a spectroscope to measure the wavelength's of the emitted photons.
The value I obtained for the Rydberg Constant is [math]\displaystyle{ R_{av}=1.09656147\times 10^7\times m^{-1} }[/math] it was only .00965% off the accepted value. So i would say that there was not too much error in collecting the data and that the error's were minimal.
The underlying quantum physics in the hydrogen spectrum is the allowable energy states that the excited electrons are able to occupy and the resulting emitted photons of certain energy levels. So there can only be certain values for the emitted wavelengths of light from the exited hydrogen gas. For the deuterium energy levels i was supposed to find that the wavelengths were shifted due to the heaver nucleus of the deuterium atom but the results were too varied for me to conclude anything from the data the error in the average was [math]\displaystyle{ R_{Deuterium}=1.0324515\times 10^{7}m^{-1} }[/math] and the error was 5.86% but i do not trust that data so i will not speculate to guess what this data means.
