Question

Define Wien's displacement law & write the value of Wien's constant .​

Answer 1

Answer:

b is a constant of proportionality called Wien's displacement constant, equal to 2.897771955... ×10−3 m⋅K, or b ≈ 2898 μm⋅K. This is an inverse relationship between wavelength and temperature. So the higher the temperature, the shorter or smaller the wavelength of the thermal radiation.

Answer 2

Answer:

Formally, Wien's displacement law states that the spectral radiance of black-body radiation per unit wavelength, peaks at the wavelength λpeak given by: where T is the absolute temperature. b is a constant of proportionality called Wien's displacement constant, equal to 2.897771955... ×10−3 m⋅K, or b ≈ 2898 μm⋅K.
