Problem: All macroscopic objects emit a continuous spectrum of radiation with a peak at a wavelength that depends on temperature. Given that the discharge tube has a temperature of about 50 degrees C, use Wien's Displacement Law to argue why we don't see a continuous spectrum when looking at the gas in the discharge tube.

Wien's displacement law:

$\overline{){{\mathbf{\lambda }}}_{\mathbf{m}\mathbf{a}\mathbf{x}}{\mathbf{=}}\frac{\mathbf{b}}{\mathbf{T}}}$

b is a constant.

b = 2.89 × 10-3

T = 50 + 273.15 = 323.15 K
