# Energetic Electrons

**Electricity and Magnetism**Level 2

Find the wavelength of the photon that radiates when an electron jumps from the \(n = 3\) energy level down to the \(n = 2\) energy level. Where is this photon in the electromagnetic spectrum?

**Assumptions**

- \(h\) (Planck's constant) = \(4.14 \times 10^-15\) eV s.
- \(c\) (Speed of light) = \(3 \times 10^8\) m/s.
- All values are approximate.
- Assume that this is a hydrogen atom.
