Balmer's Series

Balmer Series

The Balmer series is a set of spectral lines of the hydrogen atom that result from electron transitions from higher energy levels (n ≥ 3) to the second energy level (n = 2). These transitions emit light in the visible spectrum. The Balmer series includes the following lines, named after their discoverer, Johann Balmer:

1. H-alpha: Transition from n = 3 to n = 2, red light with a wavelength of about 656 nm.
2. H-beta: Transition from n = 4 to n = 2, blue-green light with a wavelength of about 486 nm.
3. H-gamma: Transition from n = 5 to n = 2, violet light with a wavelength of about 434 nm.
4. H-delta: Transition from n = 6 to n = 2, violet light with a wavelength of about 410 nm.

These lines can be observed in the emission spectrum of hydrogen and are crucial in the study of atomic structure and quantum mechanics.
