👉 Light particles, also known as photons, are fundamental components of electromagnetic radiation and are considered massless, meaning they have no rest mass. These particles are the quanta of light and exhibit both wave-like and particle-like properties. The duration of light particles is incredibly brief; a single photon can travel vast distances through space in fractions of a second, typically taking about 8 minutes and 20 seconds to reach Earth from the Sun, due to the finite speed of light (approximately 299,792 kilometers per second). However, when considering the time it takes for photons to interact with matter or travel specific distances, such as in optical experiments or over astronomical scales, the duration can vary significantly. For instance, in a typical laboratory setting, a photon might take mere picoseconds (10^-12 seconds) to traverse a distance of one meter, but in cosmic phenomena, the journey can span billions of years.
