Plank's Law, also known as Planck's Quantum Theory of Black Body Radiation, states that the energy (E) emitted by a black body at a given temperature (T) is proportional to the frequency (ν) raised to the fourth power. In mathematical terms, E = h*c^2*ν^4/c^5*(1/e^(h*c*ν/kT)-1), where h is Planck's constant, c is the speed of light, and k is Boltzmann's constant.
