Rydberg Equation Calculator
1/λ = R Z² (1/n₁² − 1/n₂²)
How to Use This Calculator
1
Enter Z, n₁, n₂
Use integers with n₂ > n₁.
2
Calculate λ
We compute the emission/absorption wavelength and frequency.
Formula
1/λ = R Z² (1/n₁² − 1/n₂²)
About Rydberg Equation Calculator
Computes wavelengths for hydrogen-like atoms and ions using the Rydberg formula.
Frequently Asked Questions
What series do n₁ values represent?
n₁ = 1 Lyman, 2 Balmer, 3 Paschen, etc.
Can Z > 1 be used?
Yes, for hydrogen-like ions (single electron), e.g., He⁺, Li²⁺.
