Optical pumping means transferring electrons
- A from ground state to motastable state
- B from metastable state to a higher excited state
- C from a state higher than the metastable state to the metastable state
- D from a state lower than the metastable state to a state higher than the metastable state
Answer & Solution
Correct Answer
(D) from a state lower than the metastable state to a state higher than the metastable state
Step-by-step Solution
Detailed explanation
Optical pumping is a process in which light is used to raise electrons from a lower energy state in an atom than the metastable state to a higher energy state than the metastable state.
