Before The Lab
Before using the apparatus in this experiment, you must complete training in the safe use of lasers detailed on the Laser Safety Training page. This includes readings, watching a video, taking a quiz, and filling out a form.
Pre-lab Discussion Questions
It is your responsibility to discuss and answer the following questions of this lab with an instructor before the first day of your scheduled laboratory period for the Pre-Lab Questions and on the 3rd & 5th day of this experiment the answers to the Mid-Lab Questions. This signed sheet must be included as the first page of your report. Without it you will lose points for this experiment (refer to the General Information of Physics 111 Advanced Lab for details). If you find it difficult to find the proper texts and articles to refresh your memory, you may find it useful to watch some of the online videos, which are designed specifically to help you with this experiment. They are titled Energy Levels, Transitions, Light Sources and Detectors, Optical Instruments, Atomic Physics. For the pre-lab, be prepared to do the following:
- Draw an energy level diagram for hydrogen. Show the transitions that produce the Balmer series. What is the formula that gives the wavelengths of these lines for the simple Bohr hydrogen atom? How does the derivation of the energy levels in the Bohr model differ from the quantum mechanical methods?
- Draw an energy level diagram for helium. Show the transitions that produce the red and yellow lines. Note the differences in the structure and splitting between the energy levels for hydrogen and helium.
- Draw an energy level diagram illustrating the Zeeman effect for the red line of helium. When a 1 tesla magnetic field is applied to helium, what happens to the energy levels and transitions that produce the red line of helium?
- Draw a sketch of the diffraction grating spectrometer showing the placement of the optical elements and the path and focusing of a light beam as it goes from the source through the spectrometer and to the film or photomultiplier. Explain how the grating works. Calculate a representative value for the resolving power of the grating.
- Draw a sketch of the Fabry-Perot interferometer showing the placement of the optical elements and the path of a light beam as it goes from the source through the interferometer and through the telescope. Calculate the resolving power of the interferometer. Why is it necessary to use the interferometer instead of the grating for observing the Zeeman Effect?
