Answer 2

Answer:

The answer to your question is an option (c). atomised, burner

Explanation:

Write down the principle of Atomic Absorption Spectroscopy.

The basis of atomic absorption spectroscopy (AAS) is that unbound atoms in the ground state may absorb light of a certain wavelength. Each element's absorption is unique; no other elements absorb this wavelength.

About the sample in atomic absorption

In an experiment, the sample ( solid or liquid) is atomized in a flame or a graphite furnace, depending on whether it is liquid or solid. After being subjected to light, generally from a hollow-cathode lamp, the free atoms undergo electronic transitions from the ground state to excited electronic states.
