A scattered spectrum of light emitted by a compound would typically be continuous.
When light interacts with a compound, such as passing through a transparent material, getting reflected or refracted by a surface, or being scattered by particles, the resulting spectrum of light is usually continuous. This means that the light covers a wide range of wavelengths with no distinct gaps or missing regions.
In contrast, a discontinuous spectrum would have distinct gaps or lines, indicating that specific wavelengths are missing. For example, an emission or absorption spectrum of an atom or molecule can be discontinuous, showing specific lines at certain wavelengths where energy is emitted or absorbed.
A rainbow-like spectrum is also continuous. A rainbow is formed when sunlight is refracted and dispersed by raindrops in the atmosphere, creating a continuous spectrum of colors from violet to red.
So, in the context of light emitted by a compound, the most common scenario is a continuous spectrum.
