12 Using LEDs to Measure Planck`s Constant
... where e is 1.6 x 10-19 Coulombs, Vthreshold is in Volts, and f is in 1/seconds. When these units are used, Planck’s constant will be in units of Joules x seconds (Js). Using the data that we collected in the first two activities and the equations found above, record and determine the values for each ...

Determination of Planck`s Constant
... where νo is the threshold frequency below which no photoemission occurs, and h is a constant. The value of h, Planck’s constant, (6.626 × 10–34 J·s = 4.136 × 10–15 eV·s), is always the same, whereas νo varies with the particular metal being illuminated. Also, within the limits of experimental accura ...
