👉 Teacher Light Particles, also known as light atoms or photons, are fundamental particles that exhibit properties of both waves and particles. They are the smallest units of light and other forms of electromagnetic radiation, such as radio waves and microwaves. These particles are crucial in various physical phenomena, including the transmission of information through fiber optics and the operation of solar cells. Unlike matter particles like protons and neutrons, which have mass, light particles are massless and travel at the speed of light in a vacuum. They interact very weakly with matter, making them essential for understanding quantum mechanics and the behavior of light in different media.
