👉 Light particles, or photons, are fundamental entities that constitute light and other electromagnetic radiation. These particles are massless and exhibit both wave-like and particle-like properties, a duality central to quantum mechanics. Photons carry energy and momentum, with their energy directly proportional to the frequency of the light they represent, as described by Planck's equation \( E = h\nu \), where \( E \) is energy, \( h \) is Planck's constant, and \( \nu \) is the frequency. Despite their lack of mass, photons travel at the speed of light in a vacuum, approximately \( 3 \times 10^8 \) meters per second, and are crucial for various phenomena, including the photoelectric effect, where they can eject electrons from materials. This particle nature of light is essential in understanding optics, quantum mechanics, and the behavior of light at the microscopic level.
