Question

explain Planck's equation​

Answer 1

Explanation:

The equation that defines Planck's constant is called the Planck-Einstein relation, and it looks like this: E = hf. Here, E is the energy of each packet (or 'quanta') of light, measured in Joules; f is the frequency of light, measured in hertz; and h is of course Planck's constant.

Answer 2

Answer:

Planck's equation describes the amount of spectral radiance at a certain wavelength radiated by a black body in thermal equilibrium.
