Hot dense objects like the filaments in an incandescent light bulb produce
A) a continuous spectrum
B) an emission spectrum
C) an absorption spectrum
D) no spectrum

Question

Quizplus · Accepted Answer

Hot dense objects like filaments in incandescent light bulbs produce a continuous spectrum, meaning it includes all wavelengths of light within a certain range. This is because the electrons in the filament are excited to higher energy levels by the heat, and as they relax back down to lower energy levels, they emit photons with different wavelengths. This produces a continuous spectrum.
