Question Detail

PHY 104 Atomic Structures Objective Question

Question

What is the fundamental principle behind Atomic Emission Spectroscopy (AES)?
Options
A Atoms absorb radiation at a specific frequency corresponding to electronic transitions.
B Atoms transit from an excited state to a ground state, emitting light at characteristic wavelengths.
Correct Answer
C Atoms absorb radiation and then re-emit it as fluorescence.
D The study of electromagnetic radiation absorbed by atoms.
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.
