Light Rays | Meaning & Types

Light isn’t just something we see — it’s something that can push, move, and apply force. 💡 In physics, every beam of light is made of tiny particles called photons. Despite having no mass, photons carry momentum, which allows light to exert real, measurable pressure on objects. When light strikes a surface, photons don’t simply vanish. They transfer momentum, creating a phenomenon known as radiation pressure ⚡ — a force strong enough to move microscopic particles and even propel spacecraft in s
