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.

FREE Expert Solution

Wien's displacement law:

λmax=bT

b is a constant.

b = 2.89 × 10-3

T = 50 + 273.15 = 323.15 K
