👉 The phrase "light particles" refers to subatomic particles that are fundamental components of light, such as photons. In a paragraph, this could be expanded to explain that these particles are incredibly small and have unique properties that distinguish them from larger matter. Photons, the most common type of light particle, are massless and travel at the speed of light, making them essential for various phenomena like electromagnetic radiation, which includes visible light, X-rays, and gamma rays. The paragraph might delve into how these particles interact with matter, their role in quantum mechanics, and their applications in technology, such as in lasers and fiber optics. It could also touch on the historical discovery of these particles and their significance in advancing our understanding of the universe.
