The light emitted from a flame is produced when electrons in an excited state absorb energy as they move to higher energy states. Thus option 2 is correct.
Energy level diagram is defined as a graphical illustration of the energies of an atom's or molecule's various orbitals.
The energy level diagram is typically shown as a sequence of horizontal lines, with each line representing an orbital.
It can also be defined as an electron shell, or energy level, can be visualized as an orbit of electrons surrounding an atom's nucleus.
Electrons absorb energy and move from ground state to exited state, and come back to original state by releasing energy.
Thus, the light emitted from a flame is produced when electrons in an excited state absorb energy as they move to higher energy states. Thus option 2 is correct.
