The electron in a hydrogen atom absorbs a photon causing the electron to jump from the state n = 2 to the state n = 5. The frequency of the absorbed photon was __________ x 10^14 Hz.

Understand that the problem involves an electron transition in a hydrogen atom, which can be analyzed using the Rydberg formula for hydrogen: $\frac{-R\left(H^2\right)}{n^2}$, where $R$ is the Rydberg constant and $n$ is the principal quantum number.
