Equivalent width: Applications, Definition & Overview

The equivalent width of a spectral absorption line is the width of the rectangle which has the same area as that between the intensity profile of the absorption line as a function of wavelength, and the continuum level, with the height of the rectangle being the magnitude of the continuum emission. It is a measure of the strength of spectral features…
