MCQ
Which source is associated with a line emission spectrum?
- AElectric fire
- ✓Neon street sign
- CRed traffic light
- DSun
✓
Answer
Correct option: B.
Neon street sign
Neon street sign gives a line emission spectrum.
When neon atoms gain enough energy to become excited, light is produced. Atom releases a photon when it returns to a lower energy state.
Therefore, the source associated with a line emission spectrum is the neon street sign.
