iSES - Internet School Experimental System

1. Read about history of quantum physics birth.
2. Recalulate examples on quantization of physical quantities in the theory section and learn about spectral lines.  (see sections Introduction and Physical background.)
3. Connect to the remote experiment and calibrate the spectrometer.
   (Measure positions of selected spectral lines of mercury lamp, their wavelenghts are easily assigned to them using table values. Proccess the calibration graphically and write the calibration function – assume linearity of the spectrometer chip. Beware, there are extra spectral lines e.g. from luminofor or glass.)
4. Using the found calibration function measure at least 5 spectral lines of Balmer series for hydrogen, use appropriately set short/long time of exposition. Answer why it neccessary to measure spectrum at least in two different time intervals.
   Beware, there are extra spectral lines, they have more complex structure and different intensity!
   Run the experiment, university level.
5. Evaulate error of wavelength measurement, compare measured values with theoretical values from equation (5).
6. Proccess measured and theoretical values in table in the protocol (protocol has also to contain date and time of remote measurement).
   In conclusion discuss difference of theoretical and measured wavelenghts and compare qualitatively intensities of spectral lines.
