Abstract (English): The widely accepted viewpoint asserts that the transverse Doppler effect for plane light waves is a red shift, a purely relativistic effect caused by the time dilation or the slowing down of a moving clock. However, rigorous proof for the assertion is absent in available literature. Here, we investigated the transverse Doppler shifts for plane and spherical waves. The results show that for plane light waves, the red shift may not be a purely relativistic effect, and the true transverse Doppler effect might be a blue shift, which might mean that a moving clock can also run faster than an identical clock at rest. For spherical light waves, the transverse Doppler effect is a blue shift when a source is at the center of a rotating disk and the receiver is at its rim; on the contrary, it is a red shift. The results might not only reflect new features of special relativity but also benefit physics teaching. [ABSTRACT FROM AUTHOR]
Abstract (French): Le point de vue largement accepte affirme que l'effet Doppler transverse pour une onde lumineuse plane est un décalage vers le rouge, qui est un effet purement relativiste causé par la dilatation du temps. Cependant, il n'existe aucune preuve rigoureuse de cette affirmation dans la littérature disponible. Dans cette étude, nous avons examiné les décalages Doppler transverses pour une onde plane et une onde sphérique. Les résultats montrent que, pour l'onde lumineuse plane, le décalage vers le rouge peut ne pas être un effet purement relativiste, et que l'effet Doppler transverse réel pourrait être un décalage vers le bleu, ce qui pourrait signifier qu'une horloge en mouvement peut également fonctionner plus rapidement qu'une horloge identique au repos. Pour l'onde lumineuse sphérique, il y a un decalage vers le bleu lorsque la source est au centre d'un disque en rotation et que le récepteur est à son bord; inversement, un décalage vers le rouge se produit dans la situation opposée. Ces résultats pourraient non seulement refléter de nouvelles caractéristiques de la relativité restreinte, mais aussi être bénéfiques pour l'enseignement de la physique. [ABSTRACT FROM AUTHOR]
