👉 Light, often perceived as a simple form of electromagnetic radiation, is actually composed of particles known as photons. These light particles are fundamental to our understanding of optics and quantum mechanics. Photons are massless, point-like entities that carry energy and momentum. They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and their behavior is governed by quantum electrodynamics (QED). The concept of light particles challenges classical notions of matter and energy, as they exhibit both wave-like and particle-like properties, a duality that is central to quantum theory. This duality is exemplified in phenomena such as the photoelectric effect, where light can eject electrons from a metal surface, demonstrating its particle nature, while also behaving as a wave in interference experiments like the double-slit experiment. Thus, the "lie" in this explanation lies in oversimplifying the complex and nuanced nature of light particles, which are far more intricate than the classical understanding of waves alone suggests.
