The Doppler Effect

Up to date, physics has neglected the crucial role of the relative velocity in the Doppler Effect. This is a small error in appearance, but it brings big problems to all of physics. Observed frequency is dependent only on the relative velocity between wavefronts and the wave source/observer. This new approach to the Doppler Effect finds application in all kinds of fields, when the source (observer) is moving.

The Doppler Effect

Abstract For any object with finite velocity, the relative velocity between them will affect the effect between them. This effect can be called the chasing effect (general Doppler effect). LIGO discovered gravitational waves and measured the speed of gravitational waves equal to the speed of light c. Gravitational waves are generated due to the disturbance of the gravitational field, and the gravitational waves will affect the gravitational force on the object. We know that light waves have the Doppler effect, and gravitational waves also have this characteristic. The article studies the following questions around gravitational waves: What is the spatial distribution of gravitational waves? Can the speed of the gravitational wave represent the speed of the gravitational field (the speed of the action of the gravitational field on the object)? What is the speed of the gravitational field? Will gravitational waves caused by the revolution of the sun affect planetary precession?

The Doppler Effect

In this paper, we present an explanation of several fundamental tests of special relativity from the perspective of the frame co-moving with a rotating observer. The solution is of great interest for real-time applications because Earth-bound laboratories are inertial only in approximation. We present the derivation of the Sagnac, Michelson–Morley, Kennedy–Thorndike and the Hammar experiments as viewed from the Earth-bound uniformly rotating frame or, as in the case of the Mossbauer rotor experiments, from the perspective of the rotating device. An entire section is dedicated to length/time measurement and to clock synchronization and another one to the Doppler effect and aberration on uniformly rotating platforms. This paper brings new information in the following areas: – new approach for clock synchronization on a rotating platform – new approach for length measurement in rotating frames – new explanation of the Doppler effect and of the Mossbauer rotor experiment – new explanation of the Kennedy–Thorndike experiment. The main thrust of this paper is to give a consistent explanation of various tests of special relativity as judged from the perspective of the rotating frame of the experimental setup. In addition, we correct certain misconceptions relative to clock synchronization and length measurement that have survived a long time in the specialty literature. A special chapter is dedicated to the derivation of the Doppler effect and of aberration in rotating frames. It is shown that such derivation is far from being trivial.

Diachronic Analysis

Even if the non-unitary nature of parties has come back into the party politics agenda, many of its features are still largely understudied. Specifically, an encompassing explanation of individual faction membership and of the role of party fusions in fostering faction membership is still missing. By performing a diachronic analysis, this article proposes a new approach to study the determinants of faction membership, highlighting the fundamental role of ideological, policy- and career-related factors. Moreover, the article uses as an explanatory factor a key element that has hitherto never been taken into account in intra-party analyses: psychological social identity, a variable that strongly conditions party members’ behaviour in situations where parties are merging. The analysis also shows the crucial role of party fusion in shaping individual faction membership determinants, highlighting that the effect of these determinants varies considerably the more time has elapsed since the party’s merger.

The Doppler Effect

The velocity of light is independent of the velocity of its source/observer. But the relative velocity between light and its source/observers is dependent on the velocity of the light source/observer, and this does not conflict with the first assumption. The velocity of light is <mml:math display="inline"> <mml:mi>c</mml:mi> </mml:math> everywhere and for everyone, but velocities <mml:math display="inline"> <mml:mrow> <mml:mi>c</mml:mi> <mml:mo>+</mml:mo> <mml:mi>v</mml:mi> </mml:mrow> </mml:math> and <mml:math display="inline"> <mml:mrow> <mml:mi>c</mml:mi> <mml:mo>−</mml:mo> <mml:mi>v</mml:mi> </mml:mrow> </mml:math> , where <mml:math display="inline"> <mml:mi>v</mml:mi> </mml:math> is the velocity of a light source/observer, do not represent the velocity of light, but the relative velocity between light and its source/observer. The velocity of light can, thus, be added to and subtracted from any velocity—giving a measurable relative velocity. A simple and common proof for this is the Doppler effect or the working of the Doppler radar. If there were no relative velocity between the electromagnetic wave and its source/observer, then there would be no Doppler effect nor would the Doppler radar work. In this paper, we will measure experimentally the relative velocity between the electromagnetic wave and the source/observer, using the Doppler effect.

Frequency Changes

When there is relative movement between an observer and a wave source the observed frequency changes by an amount depending on the relative velocity. This is the doppler effect, and it has been realized for a number of years that it might be the means of measuring the speed of an aircraft over the ground, using radio waves transmitted obliquely and received again at the aircraft after being scattered at the surface of the Earth. By 1937 radio techniques had developed so far that letters patent were granted for systems which then appeared to be practical. A number of severe problems remained, however, and not until the close of the war did development programmes to resolve these problems make headway. Since that time equipments have been successfully produced, both here and in the United States of America, and sufficient operational experience has been gained for the value of the process as an aid to navigation to be assessed.
