  • Scientists often refer to the Planckian distribution when discussing thermal emissions from stars.

  • In his research, he analyzed the properties of light to ensure they followed the Planckian law of radiation.

Morphology

Planckian = Planck (semi-transparent) = Planck + ian

Formed by the regular adjectival suffix '-ian' from the proper name 'Planck'; the morphological relation is clear but the meaning is specialized and requires knowledge of the scientist and technical context.

Etymology

Planckian comes from the name Planck, after the German physicist Max Planck who showed how a perfect hot object gives off light and heat in a regular way now called Planck's law. So, Planckian means 'following Planck's law' or showing the kind of spectrum that law predicts.
