Browsing: Photons
Photons are elementary particles that represent the quantum of light and all other forms of electromagnetic radiation. They are unique in that they have zero mass, do not decay spontaneously, and always move at the speed of light in a vacuum. Photons exhibit both wave-like and particle-like properties, a duality that is fundamental to quantum mechanics. They are emitted in many natural processes, such as during electron transitions in atoms, and are essential for technologies like lasers, photodetectors, and solar cells. In addition to carrying energy, photons also carry momentum and can exert pressure upon objects, an effect exploited by technologies such as solar sails in space exploration.
