👉 Light particles, often referred to as photons, are fundamental components of electromagnetic radiation and play a crucial role in our understanding of the physical world. These particles are massless and travel at the speed of light, approximately 299,792 kilometers per second in a vacuum. Despite their lack of mass, light particles exhibit both wave-like and particle-like properties, a concept central to quantum mechanics. In essence, light particles are discrete packets of energy, each carrying an amount of energy proportional to the frequency of the electromagnetic wave they represent, as described by Planck's equation \( E = hf \), where \( E \) is energy, \( h \) is Planck's constant, and \( f \) is frequency. This dual nature of light particles—both as waves and as discrete entities—explains phenomena such as the photoelectric effect and interference patterns, bridging classical physics and quantum theory.
