Photon is synonymous with which term?

Explanation:
Light energy in quantum theory is quantized into discrete packets called quanta. A photon is the smallest unit of electromagnetic energy, the quantum of light. Because it represents a single quantum of energy that light can carry, the term that is synonymous with photon is quantum. The energy of a photon depends on frequency (E = hν), and it behaves as both a particle and a wave, yet it has no rest mass. The other terms don’t describe this fundamental unit: electrons and protons are massive subatomic particles, and penumbra refers to the partial shadow region in radiographic images.
