Light exhibits particle-like properties due to its quantization into discrete packets of energy called photons. Photons have a fixed amount of energy, which depends on their wavelength, and they carry no mass. This dual nature of light, exhibiting both wave-like and particle-like properties, is known as wave-particle duality. The Photoelectric Effect: Demonstrating Photon Behavior One … Read more

The particle theory of light, proposed by Sir Isaac Newton in the late 17th century, posits that light consists of a stream of particles called “corpuscles.” This theory, detailed in Newton’s 1704 publication “Opticks,” dominated the scientific understanding of light for over a century until the early 19th century, when evidence for the wave nature … Read more
