Stefan's block body radiation law can also be derived from ______________ law?
Correct answer: B. Planck's
- A. Kirchoff's
- B. Planck's
- C. Fourier's
- D. None of these
Explanation
Integrating Planck's spectral blackbody radiation law over all wavelengths gives the Stefan-Boltzmann law. Kirchhoff's law relates emission and absorption but does not directly produce the total radiation law.
