Exempel på hur man kan använda BLUESHIFT i en mening

• Light from an object with a substantial relative radial velocity at emission will be subject to the Doppler effect, so the frequency of the light decreases for objects that were receding (redshift) and increases for objects that were approaching (blueshift).
• The transverse Doppler effect (TDE) may refer to (a) the nominal blueshift predicted by special relativity that occurs when the emitter and receiver are at their points of closest approach; or (b) the nominal redshift predicted by special relativity when the receiver sees the emitter as being at its closest approach.
• Wolf predicted a new mechanism that produces redshift and blueshift, that is not due to moving sources (Doppler effect), that has subsequently been confirmed experimentally (called the Wolf effect).
• Gravitomagnetic frame-dragging effects cause a receding mass to pull light away from us, reducing the momentum of the signals that it aims in our direction, so that we perceive a redshift, while the corresponding effects due to an approaching body drag light towards us, increasing the signal's detected momentum and creating a blueshift (momentum exchange).
