Red shift is the phenomenon where light from an object in space appears to have a longer wavelength, shifting towards the red end of the spectrum. It is caused by the stretching of light waves due to the expansion of the universe, known as the Doppler effect.

Is the big bang theory supported by the blue violet shift?

Outside of our Local Group, no galaxy gives off light that exhibits a blue-shift. You most likely meant to say "red shift."


What is an area that's not currently being studied?

Hubble's red shift is due to movement, however, a large mass (star) will gravitationally cause a red shift. The former is studied; the latter is not.


What creates the phenomeon known as red shift?

Two things can cause red-shift:- The rapid motion of an object away from the observer. This is known as the Doppler-effect.- Expansion of space between the object and the observer.


When was The Red Shift created?

The Red Shift was created in 2005-06.


What did Taylor shift look like when she was little?

If you meant SWIFT, do a Google image search. If you meant SHIFT, do the same exact thing.


What is the opposite of the red shift?

The opposite of red shift is blue shift. Blue shift occurs when an object is moving towards an observer, causing a shift of light towards the blue end of the spectrum due to Doppler effect.


What is meant by harsh shift in automatic transmission?

A harsh shift on a transmission is when the driver of a vehicle can hear or feel the gearbox shifting. Sometimes the gearbox will lock and not shift causing the rev limiter to reach the red line. When it finally shifts the car will shake and jolt forward.


Can a red shift and a blue shift exist on the same object at the same time?

No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.


What would red shift do to helium's Fraunhofer lines?

Red shift would cause helium's Fraunhofer lines to shift towards the red end of the spectrum. This occurs because as the light from the helium source is redshifted, the wavelengths of the spectral lines observed would also increase, causing them to appear at longer wavelengths.


What is the shift in the light of a galaxy toward the red wavelength called?

This phenomenon is called red shift.


What is the red shift of hydrogen?

The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
