No, but they are closely related.
Doppler effect is a change of frequency related to relative movement of source and observer. Depending on the relative movement, the perceived frequency may increase or decrease.
The term redshift is used specifically in the case of electromagnetic waves (such as light), and specifically if the source and the observer are moving away from each other. In this case, the frequency of the light will decrease.
What else can I help you with?
Does the Doppler effect only apply to sound waves?
No
Does the Doppler effect happen with light?
Yes, the Doppler effect can be applied to light. Any wave function can be subject to the Doppler effect if there is relative motion between the source and an observer. That's how we know that the Universe is expanding.
Is true of the Doppler effect?

What is the Doppler effect and how does it alter the way you perceive radiation?
The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. In terms of radiation, the Doppler effect can shift the frequency of electromagnetic waves emitted by a moving source, affecting how the radiation is perceived. This shift can be observed in phenomena like redshift in astronomy for light from distant galaxies moving away from Earth.
What is the change in frequency of a wave produced by a moving source?
The change in frequency of a wave produced by a moving source is known as the Doppler effect. If the source is moving towards the observer, the frequency appears higher (blueshift), and if the source is moving away, the frequency appears lower (redshift). This effect is commonly observed in everyday experiences such as the sound of a passing siren.
How does the Doppler effect measure speed of stars and movement towards or away?
redshift
How did you discover the universe is expanding?
This can be seen from the redshift of distant galaxies - normally attributed to the Doppler effect.
How are the redshift and Doppler effect similar?
The redshift and the Doppler effect are similar in that both describe changes in the frequency of waves due to the relative motion between a source and an observer. The Doppler effect refers to the change in frequency of any wave (sound, light, etc.) as the source moves toward or away from the observer. Redshift specifically refers to the increase in wavelength (or decrease in frequency) of light from celestial objects moving away from us, which is a consequence of the Doppler effect applied to electromagnetic waves. Both phenomena illustrate how motion can alter our perception of wave characteristics.
What shift did hubble see that supported the big bang theory?
Redshift; the generally accepted explanation for the redshift of distant galaxies is that it is cosmological redshift, caused by the expansion of the Universe. This is somewhat related to the idea of the Doppler effect.
Why are redshift and blueshift useful in the study of the universe?
Redshift and blueshift are manifestations of the Doppler effect. This lets us determine whether a star, or a galaxy, is moving towards us, or away from us.
Does the Doppler effect only apply to sound waves?
No
What creates a red shift?
On short distances (ie. within a few million lightyears), the redshift we see is the direct result of the Doppler effect. The Doppler effect causes light from receding sources to be less energetic, and thus red-shifted. On distances exceeding that, redshift can be attributed to the metric expansion of the universe. In cosmological redshift, the shifting of frequencies is basically caused by the stretching of space the light is passing through, and the stretching of the light wave with it.
How are redshifts created?
A redshift can be created by several mechanisms; one that is of great interest to astronomers is the Doppler effect: if an object comes towards us, or goes away from us, the frequence of the light we receive from that object, changes.A redshift can be created by several mechanisms; one that is of great interest to astronomers is the Doppler effect: if an object comes towards us, or goes away from us, the frequence of the light we receive from that object, changes.A redshift can be created by several mechanisms; one that is of great interest to astronomers is the Doppler effect: if an object comes towards us, or goes away from us, the frequence of the light we receive from that object, changes.A redshift can be created by several mechanisms; one that is of great interest to astronomers is the Doppler effect: if an object comes towards us, or goes away from us, the frequence of the light we receive from that object, changes.
How and did they figure out about the big bang?
One important clue is the Doppler effect - the redshift of distant galaxies. It turns out that the greater the distance to a galaxy, the faster it moves away from us.One important clue is the Doppler effect - the redshift of distant galaxies.

What is the red shift of light from most galaxies is evidence that?
The most plausible explanation for the redshift is that galaxies are moving away from us. This is similar to the Doppler effect, but it is normally believed that space itself is expanding, so the situation is a bit different from the "normal" Doppler effect.
What has to happen for the Doppler effect to occur?
The Doppler effect is defined as an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
How does redshift support the notion of the expanding universe?
The redshift of distant galaxies is believed to be a result of the Doppler effect - in other words, the light is shifted towards lower frequencies ("redshifted") due to the fact that the galaxies move away from us.
