when returning from the excited state to the ground state.
The intensity of the absorbed light is proportional to the
concentration of the element in the flame.
Energy is absorbed or emitted,
when an electron moves from one
state to another. The emission
spectrum consists of groups of
discrete lines corresponding to
electronic transitions.
The concentration is calculated based on
the Beer-Lambert law. Absorbance is directly proportional to the concentration of the
analyte absorbed for the existing set of conditions. The concentration is usually determined
from a calibration curve, obtained using standards of known concentration
