Planck’s Constant Experiment Viva Quiz
To determine the Planck’s constant, in this experiment we use 3-4 different colors light emitting diodes. We observe the stopping potential of each LED and plot it with the frequency or wavelength to calculate the value of Planck’s constant. The quiz is helpful to you to understand the basic concepts of the semiconductor diode. Check ...
