👉 Roughly, light particles, also known as photons, are fundamental units of electromagnetic radiation that travel through space at the speed of light. These particles are massless and have no electric charge, making them incredibly lightweight compared to other subatomic particles like electrons or protons. Photons are the primary carriers of light and other forms of electromagnetic radiation, such as radio waves and X-rays. When light interacts with matter, photons can be absorbed, reflected, or transmitted, which is why we see objects illuminated by light. The energy of a photon is directly proportional to its frequency, meaning higher-frequency light (like blue or violet) carries more energy than lower-frequency light (like red). This property of photons explains phenomena like the photoelectric effect and underpins many technologies, from solar panels to fiber optics.
