👉 The delay observed in light particles, often referred to as photons, arises from the fundamental nature of light and its interaction with matter and the medium through which it travels. Light particles, or photons, are massless and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. However, when light encounters obstacles, such as particles or materials, or passes through different media like air, water, or glass, it can be absorbed, scattered, or refracted. These interactions cause a delay because the photons must interact with the medium, which slows them down relative to their speed in a vacuum. Additionally, the time delay can also be influenced by the distance light travels and the refractive index of the medium, leading to phenomena like dispersion and chromatic aberration. In some cases, such as in fiber optics, the delay is more pronounced due to the physical constraints of the medium, but even in straight paths, light experiences a measurable delay when interacting with its environment.
