* Continuous Spectrum: A continuous spectrum is produced by an incandescent (very hot) object like a blackbody. It shows a smooth distribution of all wavelengths of light without any gaps or missing colors.

* Absorption Spectrum: The solar spectrum is actually an absorption spectrum. The Sun's core produces a continuous spectrum of light. However, as this light passes through the Sun's atmosphere, certain wavelengths are absorbed by atoms and molecules in the atmosphere. This absorption leaves dark lines (called Fraunhofer lines) at specific wavelengths within the otherwise continuous spectrum.

In summary: The solar spectrum appears continuous to the naked eye, but upon closer inspection, it reveals the presence of dark lines, indicating that it's actually an absorption spectrum.
