Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the symbol?R∞ (for infinite nuclear mass) or RH (for hydrogen)
2. What is the discoverer?Johannes Rydberg (empirical formula), theoretical basis by Niels Bohr and others
3. Why did scientists like Johannes Rydberg use it?He used it to put many different light colors into one simple formula. It let him match the wavelengths of light from many atoms.
4. How does the Rydberg constant connect to quantum theory?Niels Bohr showed that the constant comes from the way electrons jump between energy levels in atoms. It can be calculated from basic constants like the speed of light and the electron charge.

Spectroscopy: The study of the interaction between matter and electromagnetic radiation as a function of wavelength.
Quantum Mechanics: The fundamental theory in physics describing nature at the smallest scales of energy and matter.
Ionization Energy: The minimum energy required to remove an electron from an atom or molecule.
Wavenumber: The number of waves per unit length, often used in spectroscopy (reciprocal of wavelength).
