QUE SIGNIFIE REDSHIFT EN ANGLAIS
Redshift
En physique, le redshift se produit lorsque des rayonnements électromagnétiques légers ou autres provenant d'un objet sont augmentés en longueur d'onde ou déplacés vers la fin rouge du spectre. En général, que le rayonnement soit ou non dans le spectre visible, «plus rouge» signifie une augmentation de la longueur d'onde - équivalent à une fréquence inférieure et à une énergie de photon inférieure, conformément respectivement à la théorie des ondes et à la théorie quantique de la lumière. Certains redshifts sont un exemple de l'effet Doppler, familier dans la modification des emplacements apparents des sirènes et la fréquence des ondes sonores émis par les véhicules à vitesse excessive. Un redshift se produit chaque fois qu'une source lumineuse s'éloigne d'un observateur. Un autre type de redshift est le redshift cosmologique, qui est dû à l'expansion de l'univers, et des sources de lumière suffisamment distantes montrent un changement de rouge correspondant au taux d'augmentation de leur distance de la Terre. Enfin, les redshifts gravitationnels sont un effet relativiste observé dans les rayonnements électromagnétiques qui sortent des champs gravitationnels.
définition de redshift dans le dictionnaire anglais
La définition de redshift dans le dictionnaire est un décalage des lignes du spectre d'un objet astronomique vers une longueur d'onde plus grande, par rapport à la longueur d'onde de ces lignes dans le spectre terrestre, généralement à cause de l'effet Doppler provoqué par la récession. l'objet Compare: blueshift.
