👉 Light particles, also known as photons, are fundamental entities that exhibit both wave-like and particle-like properties. When light interacts with matter or other light sources, it can be described by its particle nature through the concept of photons. These particles of light travel at an incredibly high speed, approximately 299,792 kilometers per second in a vacuum, and carry discrete amounts of energy proportional to their frequency, as described by Planck's equation (E = hf). This particle behavior is crucial in phenomena such as the photoelectric effect, where light hitting a metal surface can eject electrons, demonstrating that light energy is quantized into packets. Additionally, the interaction of light particles with atoms and molecules can lead to various optical effects, including reflection, refraction, and absorption, which are essential for understanding how light behaves in different media and applications like lenses and solar cells.
