Question

what is plank's quantum theory and what is plank's constant?

Answer 1

describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T. Planks constant is h and having value as 6.627*10^-34.

hope u it is useful

Answer 2

Answer:

Theory. Planck's constant (h), a physical constant was introduced by German physicist named Max Planck in 1900. The significance of Planck's constant is that 'quanta' (small packets of energy) can be determined by frequency of radiation and Planck's constant
