Answer / suneetha verma
Flame emission spectroscopy (FES) is a form of emission
spectroscopy in which energy is provided to a sample
through use of a flame. This energy is absorbed by the
sample by promoting its electrons to a higher energy level.
The energy is used in doing work against the electrostatic
attraction between the electrons and the nucleus.
After a short period of excitation, the electrons drop back
to their previous, more stable state known as the ground
state and the absorbed energy is emitted. The wavelength
and intensity of this emitted radiation can be measured,
resulting in an electromagnetic spectrum.

FES is a form of emission spectroscopy in which heat
energy is provided to a sample through use of a flame. This
energy is absorbed by the sample by promoting its electrons
to a higher energy level.After a short period of excitation
the electrons drop back to their previous, more stable
state known as the ground state and the absorbed energy is
emitted in the form of quanta (hu). This emmited energy is
different for different atoms ,& is recorded by ditector to
identify molecule or atom .
