Question

What are the mathematical formulas proposed wien to understand black body radiation?

Answer 1

Explanation:

energy is quantized. E = hf. Planck's law is a formula for the spectral radiance of an object at a given temperature as a function of frequency (Lf) or wavelength (Lλ). When these functions are multiplied by the total solid angle of a sphere (4π steradian) we get the spectral irradiance (Ef or Eλ). c = 299,792,458 m/s.

Answer 2

All objects with a temperature above absolute zero (0 K, -273.15 oC) emit energy in the form of electromagnetic radiation. A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none.
