👉 Lincoln: Light Particles, or photons, are fundamental entities that describe the quantized nature of electromagnetic radiation, including visible light. Proposed by Albert Einstein in 1905 as part of his explanation for the photoelectric effect, these particles represent discrete packets of energy, each carrying an amount proportional to the frequency of the light they emit or absorb. Unlike classical waves, which can have any energy, photons have both particle-like and wave-like properties, embodying the dual nature of light. They travel at the speed of light in a vacuum and interact with matter by transferring energy, which is crucial for phenomena like photosynthesis, vision, and solar energy conversion. The concept of light particles revolutionized our understanding of optics and quantum mechanics, laying the groundwork for modern physics.
