   What is Wien's displacement law?

   • Wien's displacement law states that - the black-body radiation curve for different temperatures will give the maximum wavelength at a particular temperature and that is inversely proportional to the temperature. Wien’s displacement law gives the black body radiation curve as shown in the concept part.

   What is the product of Wein's displacement law?

   • According to Wein’s displacement law, the product of wavelength (λ max) corresponding to the maximum monochromatic emissive power and the absolute temperature of a black body (T) is constant. Given T = 2000 K, λ max = ? The spectral distribution of radiation from a black body at T 1 = 3000 K has a maximum at wavelength λ max.

   What is Wien's law?

   • Wien’s law is stated as follows: λ m T = C, where C is 2898 μm.K and λ m is the wavelength at which the emissive power of a black body is maximum for a given temperature T. The spectral hemispherical emissivity (ε λ) of a surface is shown in the figure below (1 Å = 10 -10 m).

   What is the difference between Planck's law and the Wien approximation?

   • In the limit of low frequencies (i.e. long wavelengths), Planck's law tends to the Rayleigh–Jeans law, while in the limit of high frequencies (i.e. small wavelengths) it tends to the Wien approximation .
