Photon is a fundamental particle of light and other forms of electromagnetic radiation. It is the force carrier for the electromagnetic force, meaning it is responsible for transmitting electromagnetic interactions between charged particles. Photons have properties of both particles and waves, and they do not have mass or electric charge. Research in the area of photons involves studying their behavior, interactions, and applications in various fields such as optics, telecommunications, and quantum mechanics. This research area explores the fundamental nature of light and how photons can be manipulated and controlled for practical applications such as lasers, photovoltaic cells, and quantum information processing. Understanding photons is essential for advancing technology and our understanding of the universe at a fundamental level.
