### Understanding Spectra This diagram illustrates the formation of three types of spectra: continuous, emission, and absorption. #### Continuous Spectrum - **Source**: Hot, dense energy source. - **Description**: The light emitted produces a continuous spectrum, which appears as an unbroken band of colors ranging from red to violet. This occurs when light passes through a prism, revealing a smooth gradient of color without any interruptions. #### Emission Spectrum - **Source**: Hot, low-density cloud. - **Description**: The light from this type of source results in an emission spectrum. Instead of a continuous display, it shows specific bright lines on a dark background. These lines represent the emission of light at particular wavelengths by the atoms or molecules in the cloud. #### Absorption Spectrum - **Source**: Hot, dense energy source with a cool, low-density cloud in front. - **Description**: When light from the hot, dense source passes through a cool, low-density cloud, we see an absorption spectrum. This spectrum appears as a series of dark lines superimposed on a continuous spectrum. These lines occur at wavelengths where the cloud's atoms or molecules absorb light. These different spectra provide critical information about the composition, temperature, and motion of astronomical objects.
