Absence of the relativistic transverse Doppler shift at microwave frequencies
An experiment is described showing that a 33-GHz microwave signal received by rotating antennas is not exhibiting the frequency shift (“transverse Doppler effect”) predicted by the relativistic Doppler formula. The sensitivity of the apparatus used has been tested to be sufficient for detecting frequency shifts as small as 10 3 Hz which corresponds to the value of (v c) = 5 10 14 used in the tr...
متن کاملComment on "The Case of Absence of Transverse Doppler Effect"
In the above paper [1], an extraordinary claim of experimental absence of the transverse Doppler effect is made. As stated in the abstract, “An experiment . . . showing that a 33-GHz microwave signal received by rotating antennas is not exhibiting the frequency shift (“transverse Doppler effect”) predicted by the relativistic Doppler formula.” In this comment, we will reanalyze the experiment a...
متن کاملTransverse flow imaging based on photoacoustic Doppler bandwidth broadening.
We propose a new method to measure transverse flow velocity based on photoacoustic Doppler bandwidth broadening, which is determined by the geometry of the probe-beam and the velocity of the transverse flow. By exploiting pulsed laser excitation and raster motor scanning, three-dimensional structure and flow velocity can be imaged simultaneously. In addition, the flow direction can be determine...
متن کاملThe Lamb Shift Experiment in Muonic Hydrogen
The subject of this thesis is the muonic hydrogen (μ−p) Lamb shift experiment being performed at the Paul Scherrer Institute, Switzerland. Its goal is to measure the 2S − 2P energy difference in μp atoms by laser spectroscopy and to deduce the proton root–mean– square (rms) charge radius rp with 10 −3 precision, an order of magnitude better than presently known. This would make it possible to t...
متن کاملResponse: The Case of Absence of Transverse Doppler Effect
A second error appears in the Comment: only one moving object (one rotating disk) had been considered according to Fig. (2). However, two moving objects (two disks rotating in opposite directions v and –v), had been used in [2], and special relativity predicts Doppler shifts between all moving objects. Hence, a shift is expected to occur for a signal emitted from a moving object (rotating disk ...
