What is the Difference Between Emission and Continuous Spectrum?
🆚 Go to Comparative Table 🆚The main difference between an emission spectrum and a continuous spectrum lies in the distribution of wavelengths of light present in each.
- Emission Spectrum: An emission spectrum consists of specific wavelengths of light with gaps between them. It is produced when an electron in an excited state moves to a lower energy level, emitting a certain amount of energy as photons. The energy levels are quantized, resulting in a spectrum with lines, where each line represents a specific energy transition.
- Continuous Spectrum: A continuous spectrum contains all wavelengths of light in a certain range, with no gaps between them. It is produced by hot, dense light sources, like the filament of an electric lamp or stars. The broad range of colors emitted by a star depends on its temperature.
In summary:
- An emission spectrum has specific wavelengths with gaps between them, produced by energy transitions in atoms or molecules.
- A continuous spectrum contains all wavelengths of light in a certain range, produced by hot, dense light sources.

Comparative Table: Emission vs Continuous Spectrum
The main difference between an emission spectrum and a continuous spectrum lies in the way they are produced and the wavelengths of light they contain. Here is a table summarizing the differences:
Feature | Emission Spectrum | Continuous Spectrum |
---|---|---|
Definition | An emission spectrum is produced when electrons in an atom are excited and then return to their ground state, emitting energy in the form of light. | A continuous spectrum is produced when light interacts with a hot, dense, glowing gas, resulting in a spectrum that contains all wavelengths in a certain range. |
Wavelengths | An emission spectrum contains specific wavelengths of light, with dark spaces between the peaks, corresponding to the energy levels of the atom. | A continuous spectrum contains all wavelengths of light in a certain range, with no dark spaces between the peaks. |
Production | Emission spectra are typically observed in atomic, molecular, or solid-state spectrometers when excited electrons return to their ground state. | Continuous spectra are produced by incandescent light sources, such as stars or heated filaments, and are often observed in spectrometers to identify the elements present in the light source. |
Both emission and continuous spectra involve the interaction of light with matter, but they have different properties and are used for different purposes in scientific studies.
