Experimental Values vs. Theoretical Values

  1. Sep 30, 2009 #1
    Hi, if say you are determining the speed of sound and you want to compare your values to the theoretical value, would you predict that your experiment values will be higher or lower than the theoretical value and why?

    Depends on how you are determining the speed of sound.

    Ha! I would have answered: "it depends on the model used to predict the velocity".

    Many important experiments were successful BECAUSE the experimenters did not believe the theoretical value was correct. In fact it wasn't.
    I recall a theoretical calculation of the electron g factor (by Karplus and Kroll) that was wrong, and the disparity with previous experiments led to a succession of new and better experiments, and a recalculation of g.
