But this doesn't define a position operator. Of course, it's all you can observe, namely the detection probability with the detector placed at a certain location. Okay, I am just looking for a meaningful way of describing "where the photon is". The shape of this distribution will depend...
Hi Guys and Gal's In answering a question in general physics I came across the following which explains at a reasonably basic level what a photon is...
What is a photon?Examines the particle nature of light in the form of photons. Quantization of the energy of light; Predictive scheme of quantum theory; Wave functions of light; Probability amplitude of photons; Quantum excitations.Marburger III...
Before even attempting to ask what a photon is "exactly" , we have to ask: do photons exist? You can go a long way believing they do not. Atoms, molecules and crystals have discrete states that determine the quantum nature of matter, so emit and absorb quanta of energy while the entity...
So if such a decay were possible, what are the limits on the lifetime of a photon? That is the question asked by a physicist in Germany, who has calculated the lower limit for the lifetime of the photon to be three years in the photon’s frame of reference. This translates to about...
Today, photonics refers to the creation, manipulation and detection of light in the service of practical applications where the particle nature of light is important. What is the Difference Between Optics and Photonics? Optics is a general area of physics covering a wide range of topics related...
Science Physics Photon What happens when an electron releases a photon?Question:What happens when an electron releases a photon?The Photon:A photon is a packet of electromagnetic energy that moves as a wave but behaves like a particle when it interacts with matter. Einstein first theorized the...

Analogy of a physical pixel on the focal plane as a photon bucket is shown. Light as an electromagnetic wave Visible light is perceived as having color. This is a property of light that is characterized by the wave phenomenon of light, electromagnetic waves. Waves can be described as having...
What is a quantum of light called? What modern-day discoveries are from quantum physics? What is an observable in quantum mechanics? What is quantum information theory? What is the fundamental assumption behind quantum mechanics? What is the photon theory of light?
