Solution
The correct answer is a. Line Spectra.
Emission spectra are always line spectra because they represent the specific wavelengths of light that a certain substance emits. These wavelengths appear as distinct lines when the light is dispersed, such as through a prism. Each line corresponds to a specific energy transition in the atom of the substance.
Band spectra and continuous spectra are different types of spectra that are not typically associated with emission spectra. Band spectra are seen in molecules where there are vibrational and rotational energy changes in addition to electronic energy changes. Continuous spectra are seen when there is a continuous range of wavelengths or frequencies, such as in white light.
