A photon's energy is equal to Planck's constant ( ) times its frequency ( ) and thus is proportional to its frequency, or inversely to its wavelength ( ).
From Planck's constant h and the Boltzmann constant k, Wien's constant b can be obtained.
Millikan is also credited with measuring the value of Planck's constant by using photoelectric emission graphs of various metals.
"Half-integer spin" means that the intrinsic angular momentum value of fermions is (reduced Planck's constant ) times a half-integer (1/2, 3/2, 5/2, etc.).
Rather, Planck's constant h was created and introduced into his new formula.
