Rydberg Constant

Postby Aashka Popat 1A » Sun Nov 03, 2019 11:45 pm

Can anyone explain what the Rydberg constant means and what we would use it for?

The Rydberg formula is a mathematical formula used to predict the wavelength of light resulting from an electron moving between energy levels of an atom.

So you'd use it for atomic spectra (since the energy at a specific shell is denoted by -hR/n^2) and you could find the frequency emitted from one level to another by doing E(final) - E(initial). You'd apply En = -hR/n^2 to the two different n values (or shells) and then subtract the two to find the change in energy, which you could apply to Bohr's Frequency Condition (change in energy = h * frequency) to find the frequency. The value of the Rydberg's constant is 3.29x10^(15) Hz.
