Doppler EffectRelative VelocityUp 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 ...
Solutions of the ordinary telegraph equation show features typical of the Doppler effect. They show the presence of a clear, sharp frequency inflection, corresponding to the moment when the source passes the observer and there is an instantaneous, abrupt change in the pitch of the sound r...
The Doppler effect is a modification of the frequency of a wave and therefore of its wavelength, when there is a relative movement between the source of the wave and the observer. Redshift is an essential tool for studying the distant universe. It makes it possible to determine the distance ...
This phenomenon, known as the Doppler effect, is due to the wave nature of sound. Loudness In general, an increase in intensity will cause a sensation of increased loudness. But loudness does not increase in direct proportion to intensity. A sound of 50 dB has ten times the intensity of ...

the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are stretched out, orredshifted. Known as the Doppler Effect, the same phenomena occurs with waves of light at all ...

However, from what I understood, the main cause of dissymmetry of the out-going and home-coming trips of the traveling twin has its explanation in the doppler effect. Whereas during the out-going trip the traveling twin observes a lesser frequency of rotation of the home-staying twin's se...
