👉 The concept of "pull" in the context of light particles, or photons, refers to the force exerted by light upon matter, though this force is typically very weak compared to gravitational or electromagnetic forces. When light interacts with particles, it can transfer momentum and energy, causing these particles to move or change direction. For instance, when light shines on a surface, it can push electrons off, creating a phenomenon known as the photoelectric effect, where electrons are ejected from a material. This interaction is fundamental in understanding how light influences matter at the quantum level, such as in solar cells where photons excite electrons to generate electricity. The "pull" of light particles is thus a subtle yet crucial aspect of light-matter interactions, underpinning various physical and technological processes.
