Meaning and Definition
A type of emission spectrum produced by a high-voltage electrical spark passing through a gaseous material or between electrodes made of a material, used primarily in spectroscopy for identifying metallic elements.
In spectroscopy, the pattern of wavelengths of light emitted when atoms in a sample are excited by a high-voltage spark. This analytical technique (spark source spectroscopy) is used for qualitative and quantitative analysis of metallic elements, especially in metallurgy and materials science.

FAQ
Frequently Asked Questions
A spark spectrum is a specific type of atomic emission spectrum, where the excitation source is a high-voltage electrical spark. Not all atomic emission spectra are spark spectra.
No, it is a highly technical term with no established metaphorical or everyday usage.
Its main application is in the identification and quantification of metallic elements in materials, especially in metallurgy, mining, and forensic science.
It is named for the method of excitation: a high-voltage electrical spark vaporizes and excites atoms in the sample, causing them to emit light at characteristic wavelengths.
A type of emission spectrum produced by a high-voltage electrical spark passing through a gaseous material or between electrodes made of a material, used primarily in spectroscopy for identifying metallic elements.
Spark spectrum is usually technical/scientific in register.
Spark spectrum: in British English it is pronounced /ˈspɑːk ˈspɛktrəm/, and in American English it is pronounced /ˈspɑrk ˈspɛktrəm/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Imagine a SPARK from a welder's torch hitting a metal sample. The colourful light bands (SPECTRUM) that come off are its unique fingerprint – the SPARK SPECTRUM.
Conceptual Metaphor
FINGERPRINT/IDENTITY CARD (The spark spectrum acts as a unique identifier for an element, much like a fingerprint identifies a person).
