👉 The chase of light particles, or photons, is a fundamental concept in physics that describes their movement through space. Photons are massless, chargeless particles that mediate the electromagnetic force, responsible for interactions like light and electricity. When light travels from one medium to another, such as from air into water, it bends—a phenomenon known as refraction—due to changes in its speed. This bending is a direct result of photons changing their direction as they transition between media with different optical densities. Additionally, when light interacts with matter, it can be absorbed, reflected, or scattered by particles, leading to complex behaviors like the scattering of sunlight in the atmosphere, which gives rise to phenomena such as the blue sky and the red hues of sunsets. The study of these interactions helps physicists understand not only light but also the underlying principles of quantum mechanics and relativity.
