# Problem: The light emitted from one of the following electronic transitions (n = 4 → n = 3 or n = 3 → n = 2) in the hydrogen atom caused the photoelectric effect in a particular metal while light from the other transition did not. Which transition was able to cause the photoelectric effect?

🤓 Based on our data, we think this question is relevant for Professor Hoffman & Ilies' class at DREXEL.

For Photoelectric Effect to occur a photon (light particle) should have sufficient energy to eject electrons on the surface of a metal.

Let’s calculate how much energy each of the light emitted has during each transition:

Use the Balmer equation to solve for wavelength (λ):
