In the photoelectric equation, which symbol represents Planck's constant?

Explanation:
Planck's constant is the factor that links the frequency of light to the energy of a photon, E_photon = h f. In the photoelectric equation, a photon must supply enough energy to overcome the work function, and any extra energy becomes the maximum kinetic energy of the emitted electron, KE_max = h f − φ. Because Planck's constant appears as h in this relation, the symbol for Planck's constant is h. The other symbols stand for energy (E), frequency (f), and kinetic energy (KE).
