ABSTRACT

Wien’s displacement law was derived from mode value of the very old Planck’s distribution for black body radiations. One more new displacement law is derived from mean value of the Planck’s distribution, by evaluating two integrals. They are used to propose definitions for temperature of electromagnetic waves.

Keywords: Planck’s distribution, Wien’s displacement law, Mean of a distribution
