I keep getting “Photon energy” questions wrong in Modern Physics. What's the trap?
treating light purely as a wave when explaining the photoelectric effect.
The usual trap: treating light purely as a wave when explaining the photoelectric effect. How to avoid it: higher frequency (bluer light) means more energetic photons. Go back to the definition — light comes in packets of energy E = hf = hc/λ.

Photon energy
Common mistake
treating light purely as a wave when explaining the photoelectric effect.
Memory tip
higher frequency (bluer light) means more energetic photons.
