Answer 1

plancks law gives the monochromatic emissive power for black bidy radiation

Answer 2

Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. The law applies only to blackbodies, theoretical surfaces that absorb all incident heat radiation.
