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 Doppler effect is discussed for flexure waves in beam and plate, three body waves (P, SV, SH) in an infinite solid, modal SH waves in a thick plate and a Rayleigh wave on the surface of a semi-infinite solid. The exact closed form solution for each elasto-dynamic problem is obtained and the simple equation for the Doppler frequency shift is derived

The problem of a massive particle moving along a stretched string and subjected to a time-varying force perpendicular to the string is treated by the method of characteristics. If the force varies harmonically explicit expressions may be obtained; these are displayed.

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.

Marine Vibrators And The Doppler Effect
Offshore Technology Conference, 1988ABSTRACT Marine seismic data acquired with a moving vibrator suffer phase dispersion caused by Doppler shifting of the source sweep function. The dispersion, which can be as large as several hundred degrees, is a function of frequency, ship speed, sweep type, and the time dips of reflection events.

Doppler effect in aeroacoustics [PDF]
The Journal of the Acoustical Society of America, 2008 Doppler effect in aeroacoustics The prediction of acoustic fallout caused at the ground level by aircraft in flight or by launchers at take-off sets the problem of the distortion of the emitted sound spectrum by the Doppler effect. Former studies applied to this problem use a geometrical formalism based on simplifying hypotheses such as homogeneous ...
