Question
What is the fundamental principle behind Atomic Emission Spectroscopy (AES)?
Correct Answer
Option B is the correct answer.
Detailed Explanation
According to the text on page 7, "Atomic emission spectroscopy (AES): This involves the principle of energy transfer as atoms transit to ground state from an excited state. Excited atoms emit light at characteristic wavelengths as they return to a lower energy state."
Hint
Think about what 'emission' means in the context of light from excited atoms.
