What is true about the light emitted by an atom?

The light emitted by an atom is called atomic emission. It is produced when an electron in an excited state returns to a lower energy state, releasing energy in the form of light. The color of the light emitted depends on the energy difference between the excited and lower energy states, and is unique to each element. This phenomenon is used in spectroscopy to identify elements and analyze their composition.

- It has characteristic wavelengths.
- It is produced when an electron makes a transition from a higher energy level to a lower energy level.
- It is quantized, meaning that it can only have certain discrete values.
- It depends on the type of atom that emits it.
- It can be used to identify the element that emits it.
