"velocity" in inglés with examples - Collocation dictionary inglés
- If the redshift is interpreted as a Doppler shift, the recessional velocity of the object can be calculated.
- When the recessional velocities are plotted against these distances, a linear relationship known as Hubble's law is observed:
- Scientists use the redshift to gauge both the recessional velocity of an object and its distance from Earth.
- Hubble is known for showing that the recessional velocity of a galaxy increases with its distance from the earth, implying the universe is expanding.
- Hubble's law is considered a fundamental relation between recessional velocity and distance.
- The relation of redshift to recessional velocity is another matter.
- Next, the connection between redshift or redshift velocity and recessional velocity is discussed.
- The redshift is usually interpreted as due to recessional velocity, which can be calculated according to the formula:
- The recessional velocity of a galaxy is usually calculated from the redshift observed in its emitted electromagnetic radiation.
- Column 8: The recessional velocity (km/s) of the galaxy relative to the cosmic microwave background.
