Essentially this question boils down to "why does the energy of light depend on frequency?".
The analogy my textbook (pg. 272 principles of chemistry A molecular Approach 3rd edition by Nivaldo J. Tro) gave was that photons with higher frequency are like baseballs, whereas photons with lower frequency are like ping pong balls. Meaning that each photon has higher energy.
This StackExchange page (In the famous Einstein's Photoelectric effect, why does the intensity of light not raise the kinetic energy of the emitted electrons?) seems to say the opposite, that the energy of each photon is the same and what changes is the amount of photons per area.
