👉 Understanding and describing light particles, or photons, presents several challenges due to their unique properties and the fundamental nature of quantum mechanics. Photons are massless, point-like particles that mediate electromagnetic interactions, yet they exhibit both wave-like and particle-like behaviors. This duality makes it difficult to conceptualize them using classical physics intuitions. Additionally, photons do not interact with matter in a way that provides direct, observable evidence of their existence, unlike larger particles. Their extremely small mass and the fact that they travel at the speed of light complicate experimental verification and theoretical modeling. Moreover, phenomena such as quantum entanglement and superposition further obscure our understanding, as these effects seem to defy classical explanations and highlight the probabilistic nature of quantum mechanics.
