In a hydrogen atom, which transition emits the photon with the highest energy?

In a hydrogen atom, which transition emits the photon with the highest energy?

Step 1: Understand that a hydrogen atom has energy levels, which are represented by 'n' values (n=1, n=2, n=3, etc.).
Step 2: Know that when an electron moves from a higher energy level (n) to a lower energy level, it emits a photon.
Step 3: The energy of the emitted photon depends on the difference between the two energy levels.
Step 4: Calculate the energy difference for the transition from n=2 to n=1. This is the largest difference among the possible transitions.
Step 5: Conclude that the transition from n=2 to n=1 emits the photon with the highest energy.
