The present experiment examines the hydrogen spectrum and calculates the electronic transition for each of the hydrogen lines. Additionally, the experiment aims at verifying the Rydberg’s constant both graphically and mathematically as well as conducting identification of unknown metal ions using flame tests of line spectra.
Substances emit electromagnetic radiation when subject to sufficient heat or current. However, different observations are recorded in the case when energized ions are subject to electric current or heat. While other substances emit continuous spectra, energized ions emit a line spectrum with each ion type having unique spectra. A spectroscope measures the wavelength of radiation using a scale calibrated using known radiations which then is used to determine the type of an unknown substance. Therefore, it is possible to examine the type of ions in an unknown source of radiation using a calibrated spectroscope. Using the Rydberg equation the electronic transition for each examined line spectra can be determined as per the spectroscope observation. The proceedings can further be used to mathematically calculate Rydberg’s constant, as the above equation. A plot against the values obtained in the experiment graphically determines the Rydberg’s constant, as the gradient of the resultant graph. Additionally, using the spectroscope’s calibrations can be used to identify the radiation from unknown metal ions using its calibration.
