Rydberg Formula Calculator for Uni-electronic Species

Calculate the wavelength of light emitted by a hydrogen-like (uni-electronic) species using:
$\frac{1}{λ} = R Z^{2} (\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}})$

* Enter the atomic number (Z), lower energy level (n₁), and higher energy level (n₂) with n₂ > n₁.

Step 1: Enter Parameters

Atomic Number,

Z

Example: 1 (for hydrogen), 2 (for He⁺)

Lower Energy Level,

n_{1}

Example: 2

Higher Energy Level,

n_{2}

Example: 3 (must be greater than $n_{1}$ )
