The Doppler effect, named for Christian Doppler (ca. 1842), has tremendous importance for science and technology. Thanks to it, air traffic controllers can distinguish among objects moving in the line of sight; on the ground, speeding cars can be identified before serious accidents occur; and in space, the velocities of the stars and the rotations and ...

An analysis of the classical Doppler effect
European Journal of Physics, 2003Summary: The Doppler effect is a phenomenon which relates the frequency of the harmonic waves generated by a moving source with the frequency measured by an observer moving with a different velocity from that of the source. The classical Doppler effect has usually been taught by using a diagram of moving spheres (surfaces with constant phase) centred ...

In every advanced course on physics the Doppler, effect is usually the standard example for demonstrating the fundamental physical differences between the propagation of elastic waves through a mechanical medium and the propagation of electromagnetic waves through our physical space.

Expressions for the Doppler effect are derived without employing any assumption about the phase of a plane wave. It is shown that the invariance of this phase under both the Galilean and the Lorentz transformations is a trivial consequence of the mathematics and, is independent of its association with any physical process.

Equivalence of the Doppler effect, relativistic Doppler effect and scattering effect
Physics Letters A, 1970Abstract On the basis of an electromagnetic plane wave scattered by an electron, the relativistic Doppler effect is demonstrated equivalent to a two step Doppler effect. Further experimental verification for the conservation law according to the Compton-Debye theory is also urged.

An angular analog of the Doppler effect arising from the quantum of angular momentum carried by circularly polarized photons is presented and developed. Applications to rotational Raman scattering, fluorescence doublets, controlled frequency shifting of light, rotation-induced optical activity, and the measurement of rotational motion of small ...

The velocity of electromagnetic radiation in a vacuum is a constant which depends only upon the magnetic permeability and electrostatic permittivity of free space. This velocity is independent of any movement of the source or observer, but the same is not true of the wavelength and frequency of radiation.
