### Rydberg Equation

Posted:

**Tue Oct 16, 2018 11:14 pm**Does Dr. Lavelle prefer that we use the difference in energy equation, and then the Bohr frequency condition, and then the c = hv equation to calculate an electron's wavelength when it transitions from a higher energy level to a lower energy level as opposed to the Rydberg equation?

In his lecture and module, he doesn't use the Rydberg equation to solve this even though this way might be faster and simpler.

Some homework problems also specify to use the Rydberg equation to solve, so I am confused on which method to use.
