Common questions

What is the Wien's Displacement Law formula?

Wien's Displacement Law is written λₘₐₓ T = b = 2.898 ×10⁻³ m·K. The wavelength at which a blackbody emits most strongly is inversely proportional to temperature. It belongs to Modern Physics, under Thermal Radiation.

What are the units in λₘₐₓ T = b = 2.898 ×10⁻³ m·K?

In SI units, \lambda_{max} is peak wavelength, measured in m; T is temperature, measured in K; b is wien's displacement constant, measured in m·K.
