Understand that different types of spectra arise from how atoms or molecules interact with light, either by emitting or absorbing specific wavelengths.
Recall that a continuous spectrum shows all wavelengths of light without interruption, like a rainbow, and is produced by a hot, dense object.
Know that an absorption spectrum appears when light passes through a cooler gas, causing certain wavelengths to be absorbed, resulting in dark lines on a continuous background.
Recognize that a band spectrum consists of groups of closely spaced lines, often from molecules, due to vibrational and rotational transitions.
Identify that a line spectrum consists of distinct, separate lines at specific frequencies emitted by atoms or molecules when electrons transition between energy levels.
