alleryStart learning →In the photon energy equation, the letter f stands for the:
AFrequency of the wave
BForce on the wave
CFocal length used
DField strength found
Answer & Solution
Correct answer: A. Frequency of the wave
1. The second symbol describes the light itself.
2. Photon energy is h times f.
3. The letter h is Planck's constant.
4. The letter f is the frequency of the associated light wave.
