Answer:
A line is formed when an electron moves to a lower energy level.
Explanation:
When an excited atom returns to a lower energy state photons of light are emitted and show on the spectrum as a line.
A line spectrum is termed after the fact that radiation (light) emitted is made up of a series of crisp lines. The wavelengths of lines are unique to an element and can create extremely complex patterns, and the further discussion can be defined as follows:
- Whenever an electron goes to the lower energy level, it forms a line.
- Once an electron goes down to a lower energy orbit, it de-excites, generating a photon of a specified frequency.
- Conversely, this photon might be emitted in any direction, not merely just like an incident photon.
Therefore, the final choice is "Option A" .
