Comparing Light Spectra from Incandescent Bulbs, Fluorescent Tubes & Sunlight

[Precursor]

Homework Statement

What are some differences between the spectrum observed for light from the incandescent bulb, the fluorescent tube, and the spectrum observed from sunlight?

The Attempt at a Solution

I think that sunlight produces an absorption spectrum, whereas both incandescent bulb and fluorescent tube both produce an emission spectrum? Am I right on this?
