Rydberg Equation in Terms of Wavelength
### Formula:
$$\frac{1}{\lambda}=R_H\left(\frac{1}{n_1^2}-\frac{1}{n_2^2}\right)$$
### Terminologies:
- λ → Wavelength of emitted or absorbed radiation.
- $$R_H$$ → Rydberg constant.
- $$n_1$$ → Lower energy level.
- $$n_2$$ → Higher energy level.
### Usage:
- Used to calculate wavelength of spectral lines.
