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 ...

The Photoelectric effect - University of Toronto Physics
... In 1899, J.J. Thomson discovered that when a metal target is irradiated by ultraviolet light it emits negative charges. These charges were found to have the same charge/mass ratio as the electron. This effect was named the photoelectric effect, and the emitted electrons called photoelectrons. To exp ...
