👉 Light particles, or photons, are fundamental entities that constitute light. These particles are massless and exhibit both wave-like and particle-like properties, a duality central to quantum mechanics. They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and carry energy proportional to their frequency, as described by Planck's equation. Photons interact with matter through various processes such as absorption, emission, and scattering, which are crucial for phenomena like photosynthesis, the operation of solar cells, and the transmission of information via fiber optics. In the environment, light particles play a vital role in ecosystems, influencing plant growth through photosynthesis, affecting animal behavior, and shaping our visual perception of the world around us. They also contribute to atmospheric processes, such as the scattering that causes the blue sky and red sunsets, and are essential for various technological applications, from lighting to communication.
