Lyman Series

### Formula:

$$n_1=1,\ n_2=2,3,4,...$$

### Terminologies:

- Lyman Series → Hydrogen spectral series formed when electrons fall to first energy level.

- $$n_1$$ → Final energy level of electron.

- $$n_2$$ → Initial energy level of electron.

### Usage:

- Used for transitions ending at first shell and lying in ultraviolet region.
