Write a Balmer formula and explin each terms

The Balmer formula is an empirical equation that relates the wavelength of light emitted by hydrogen to the energy levels of the electron in the atom. It is given by:

1/λ = R * (1/2^2 - 1/n^2)

where:
- λ is the wavelength of the emitted light
- R is the Rydberg constant, equal to 1.0973731568508 x 10^7 m⁻¹
- n is an integer representing the energy level of the electron (n ≥ 3)

Let's break down each term in the formula:

1. 1/λ: This represents the reciproca
