Two light sources are provided: a hydrogen discharge tube and a filament lamp. Each can be viewed through a grating fixed to the glass case. If you maneuver your eye until you see a bright fringe pattern, which type of spectrum you see for each light source?© BrainMass Inc. brainmass.com March 4, 2021, 9:19 pm ad1c9bdddf
A filament lamp radiates as a black-body. The source of the radiation is the heat caused by the resistance to the electron's flow through the metal filament.
Black-body radiation is continuous; it emits EM radiation in all frequencies. However, not all frequencies are emitted with the same intensity. The intensities are distributed according to Maxwell-Boltzmann distribution.
The width and peak of the distribution of intensities is determined by the temperature of the ...
This response discusses what the light spectrum of two different light sources would be.
