👉 Len: Light Particles, often referred to as photons, are fundamental particles that constitute light and other electromagnetic radiation. These particles are incredibly small, far smaller than atoms or even molecules, and they exhibit both wave-like and particle-like properties, a concept known as wave-particle duality. Len describes light particles as discrete packets of energy, each carrying an amount proportional to the frequency of the light. This quantized nature of light particles was a cornerstone in the development of quantum mechanics. They travel at the speed of light in a vacuum and interact with matter through various processes, such as absorption, emission, and scattering. Understanding len is crucial for explaining phenomena like the photoelectric effect, where light can eject electrons from materials, and the behavior of light in different media.
