SUMMARY
Relative intensity in spectra refers to the intensity of light detected within a specific wavelength band as measured by a particular spectrograph. This measurement varies based on the instrument's sensitivity, such as CCD efficiency, and the observational conditions, including whether the observation occurs during twilight or nighttime. It is distinct from specific intensity, which is defined as intensity per unit frequency or wavelength. Understanding these differences is crucial for accurate spectral analysis.
