SUMMARY
The discussion centers on the differences in light spectra produced by incandescent bulbs, fluorescent tubes, and sunlight. It is established that sunlight generates a continuous spectrum, while incandescent bulbs emit a broad emission spectrum due to thermal radiation. In contrast, fluorescent tubes produce a discrete emission spectrum characterized by specific wavelengths corresponding to the gas used. This distinction is crucial for understanding the applications and effects of different light sources.
