What causes atoms and molecules to emit radiation in various regions of the electromagnetic spectrum?

Options

  1. AInteraction with matter
  2. BAbsorption of energy
  3. CHigher energy states
  4. DDecreased stability

Correct answer

C. Higher energy states

Step-by-step solution

Atoms and molecules may absorb energy and reach higher energy states when interacting with electromagnetic radiation. To return to their more stable, lower energy states, they emit radiation in various regions of the electromagnetic spectrum.
