# Problem: Which electron transition produces light of the highest frequency in the hydrogen atom?a) 5p → 1sb) 4p → 1sc) 3p → 1sd) 2p → 1s

We’re being asked to determine the electron transition that produces light of the highest frequency in the hydrogen atom. Recall that starting from n = 1, the distance between each energy level gets smaller as shown below:

All of the given transitions involve going from a higher energy level to a lower energy level: this means emission is involved. Recall that the energy of a photon is given by:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{h\nu }}}$

We can see that energy and frequency are directly proportional: higher energy means higher frequency.
