Why do photons oscillate?
photons do not have mass. There is no evidence of intrinsic photon oscillations of any kind. The “frequency” associated with a photon is just another way of expressing it’s momentum and kinetic energy. It is used because of the connection between photons and electromagnetic waves (which do oscillate).
Why do particles oscillate?
In an oscillating system, the force always acts in a direction opposite to the displacement of the particle from the equilibrium point. This force can be constant, or it can vary with time or position, and is called a restoring force. As long as the force obeys the above principle, the resulting motion is oscillatory.
What causes waves to oscillate?
Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction. Matter in the medium is periodically displaced by a sound wave, and thus oscillates.
Why does a photon move in a wave?
Just like, a particle with mass moves because of gravitational field. a particle with charge moves because of electric field.
How does a photon oscillate?
The strength of the electromagnetic field oscillates as the wave propagates. A charged particle will oscillate in response to a passing electromagnetic wave. Light is the signal passing between charged particles. In a medium, the photons of light (light particles) interact with matter particles.
Do particles oscillate?
“Particles” do not oscillate in QM or QFT. The formal QM description of matter would state that the elementary constituents of matter can behave as a particle and/or a wave.
Why do neutrinos oscillate?
Neutrino oscillation occurs when neutrinos have mass and non-zero mixing. This is because the muon neutrinos passing through the earth turn into tau neutrinos. The discovery of neutrino oscillation verified that neutrinos have a small but finite mass.
Why do electrons oscillate?
If an electron is moved from its equilibrium position, the resulting positive charge exerts an electrostatic attraction on the electron, causing the electron to oscillate about its equilibrium position.
Why do electric fields oscillate?
This charged particle creates an electric field (which can exert a force on other nearby charged particles). When it accelerates as part of an oscillatory motion, the charged particle creates ripples, or oscillations, in its electric field, and also produces a magnetic field (as predicted by Maxwell’s equations).
Why don’t photons oscillate?
— again, the answer explained that photons aren’t really “particles of light”, and don’t oscillate, but again no satisfactory answer to the “why” question was included. Finally, this pagehas a great applet demonstrating the basic principle of how disturbances in one charge propagate to nearby ones.
What causes electromagnetic waves to occur?
As you probably already know, electromagnetic waves are generated by moving electrons. An electron generates an electric field. A moving electron generates a magnetic field. These combined electrical and magnetic waves reinforce one another, giving rise to an electromagnetic wave.
What is the energy of a photon?
An emitted physical photon oscillates at a certain frequency (has an energy) related to the loss of energy at the source. A simplified description would say that a certain bound electron in an atom itself oscillates at frequency f1, falls to f2, and emits a photon of f=f1-f2, as an example.
Why is the oscillation provided by a spring?
The oscillation is provided by a spring for illustration purposes. The text naturally raises the question: “Yeah, that all makes sense, but don’t expect me to believe that particles as small as electrons are attached to springs.
