Rydberg formula (wavelengths) (1/λ = R_H Z² (1/n₁² - 1/n₂²))
jee-advancedjee-mainneet-ug
1/λ = R_H Z² (1/n₁² - 1/n₂²)
What each symbol means
| Symbol | What it stands for |
|---|---|
| R_H | Rydberg constant ≈ 1.097×10⁷ m⁻¹ (for infinite nuclear mass) |
| n_1 | Lower level (final) |
| n_2 | Higher level (initial), n₂ > n₁ |
When to use this
Emission spectrum hydrogenic atom; vacuum wavelength; non-relativistic.
