Solution Summary

This response discusses what the light spectrum of two different light sources would be.

Solution Preview

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 ...
