From Balmer's series calculation, first line in the $\mathrm{H}$ spectrum exhibits wavelength of $656.1 \mathrm{~nm}$. Bohr's theory supports almost similar kind of radiative transition by transition of electron of $\mathrm{H}$ atom from third to second energy level. From this, find the value of the Rydberg constant.

Key Concepts

Balmer Series

The Balmer series is a group of spectral line emissions in hydrogen that result from electron transitions from higher energy levels down to the n=2 energy level. It was one of the first sets of observations that led to the recognition of quantized energy levels in atoms and provides a straightforward empirical relationship for the wavelengths of light emitted in these transitions.

Bohr Model

The Bohr model of the atom introduces the concept that electrons orbit the nucleus in defined paths with discrete energy levels. Transitions between these levels result in the emission or absorption of photons with energies that precisely match the energy differences, thereby explaining the observed hydrogen spectral lines and validating the idea of quantized atomic structure.

Rydberg Constant

The Rydberg constant is a fundamental physical constant used in the Rydberg formula, which predicts the wavelengths of light emitted by electrons in hydrogen as they transition between energy levels. Its value encapsulates the underlying characteristics of the hydrogen atom and is crucial for accurately describing and calculating the positions of spectral lines.

Quantum Transitions

Quantum transitions refer to the changes of electrons between distinct, quantized energy states within an atom. When an electron undergoes such a transition, it emits or absorbs a photon whose energy corresponds exactly to the difference between these states, leading to the characteristic spectral lines observed in experiments.
