Question Detail
Question
Which type of atomic spectroscopy involves atoms emitting light at characteristic wavelengths as they return to a lower energy state from an excited state?
Correct Answer
Option B is the correct answer.
Detailed Explanation
According to the text, '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 whether the atoms are 'absorbing' or 'emitting' energy as they move to a lower state.
