FWHM Meaning and
Definition
-
The acronym FWHM stands for Full Width at Half Maximum. It is a measurement used in various scientific and technical fields to describe the width of a curve, peak, or function at its halfway point. FWHM is calculated by finding the interval between the two points on the curve where the value is equal to half of the maximum value.
In physics and optics, FWHM is often used to characterize the spectral lines of light sources, such as lasers or lamps. It represents the range of wavelengths or frequencies over which the intensity of the light is at least half of its peak intensity. A narrower FWHM indicates a more focused and intense spectral line, while a broader FWHM suggests a wider range of wavelengths or frequencies contributing to the source.
In signal processing and data analysis, FWHM serves as a crucial parameter for quantifying the bandwidth or resolution of a signal or distribution. It provides an estimate of the spread or dispersion of the data around its central value. A smaller FWHM indicates a narrower distribution or more localized data points, while a larger FWHM implies a broader distribution or more dispersed data.
Overall, FWHM is a valuable metric used to characterize and compare various phenomena, enable detailed analysis of their properties, and facilitate precise measurements in fields such as physics, optics, spectroscopy, signal processing, and statistics.
