| Abstract: | The paper uses reflection and refraction taking place in two medium interfaces to be an example,reaching a conclusion of the entropy increase during the separating process.Then from thermodynamics,the paper gives the qualitative illustration on such conclusion;from quantum statistics,it makes the quantitative proof.Finally it explains the reason for the increase of entropy from thermodynamics and statistical physics. |
