摘要
黑体辐射的普朗克公式中,辐射能量密度的频率表示(ρ_ν)和波长表示(ρ_λ)曲线顶点对应的频率值和波长值不相对应,针对这一貌似矛盾的结果,进行了详细深入地讨论说明,发现这一问题的本质在于ρ_ν和ρ_λ的定义以及波长和频率的非线性关系.
In black- body radiation, the frequency-coordinate of the vertex of the Planck formula 10t doesn't correspond with the wavelength - coordinate of the vertex of the Planck formula ρλ.The seemingly contradictory result brings about confusion in the actual learning process of the students . After an in - depth analysis, we find that the key to the essence of the problem lies in the exact understanding of the two concepts ρV and ρλ and the fact that the relationship between frequency and wavelength is not linear.
