... Each photon has an energy hν, so the total # of photons needed to produce energy E is E/hν. The frequency of the radiation (ν = c/λ=?) and the total energy (?) emitted by the lamp E =?. E = P∆t, P - the power (in watts), ∆t - the time interval for which the lamp is turned on. • Answer: The number of ...

... that shows up, with major consequences. Because of this, there is a theorem, due to Bargmann [1], that says that one cannot make a coherent superposition of two different mass states of a particle, non-relativistically. This theorem follows directly from this phase factor, which is mass dependent. B ...

Originally Einstein had only the tensor equation for vacuum but with that he was able, effectively, to study the gravitational field of the sun (amounting, in precise form, to a Schwarzschild solution). And that was sufficient to consider the gravitational deflection of light rays passing near the s ...

... Quantum mechanics has a profound influence on the philosophy of nature. Indeed, it has altered our view of objective reality and classical determinism. In quantum theory, what you know is what you measure (or what some physical system “records”). The acts of measurement and observation can create th ...

Propagator

In quantum mechanics and quantum field theory, the propagator gives the probability amplitude for a particle to travel from one place to another in a given time, or to travel with a certain energy and momentum. In Feynman diagrams, which calculate the rate of collisions in quantum field theory, virtual particles contribute their propagator to the rate of the scattering event described by the diagram. They also can be viewed as the inverse of the wave operator appropriate to the particle, and are therefore often called Green's functions.
