Why doesn't the Doppler shift appear when an observer moves toward the source?
Doppler's effect does not happen when the observer is moving towards the source because unlike the source when observer moves forward the waves are not compressed and they pass the observer without being compressed and since the doppler effect is due to the Change in wavelength of the wave, it fails to occur.
Is toasting bread a chemical change or a physical change?
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
Does there occur any change in melting point of ice by variation of pressure?
Yes, increase in pressure causes the freezing point to drop.
Where did red and blue shift occur?
Redshift and blueshift occur in astronomy when the wavelength of light from an object is stretched (redshift) or compressed (blueshift) due to the Doppler effect. Redshift is seen in objects moving away from us (e.g., galaxies in the universe expanding), while blueshift occurs in objects moving towards us (e.g., stars in our own galaxy).
When a change in DNA causes to be read incorrectly its called a?
When a change in DNA causes it to be read incorrectly, it is called a mutation. Mutations can lead to alterations in the amino acid sequence of proteins, potentially resulting in changes to their function or stability. They can occur due to various factors, including environmental influences or errors during DNA replication. Some mutations may have no effect, while others can lead to diseases or advantageous traits.
For the Doppler effect to occur what has to happen?
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.

For the Doppler effect to occur?
For the Doppler effect to occur the measured object must be in motion (radial velocity) relative to the emitter of a wave.
What is the Doppler effect What causes it to occur?
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. It occurs because the movement of the observer changes the effective distance between the observer and the wave source, leading to a perceived shift in the frequency of the wave.
For the Doppler effect to occur what must happen?
For the Doppler effect to occur, there must be relative motion between the source of the wave and the observer. As the source moves towards or away from the observer, the frequency of the wave appears to change, causing a shift in the perceived wavelength.
Does Doppler effect occur for all types of waves?
yes
Does the Doppler effect occur for only some types of waves or all types of waves?
The Doppler effect can occur for all types of waves, including sound waves, light waves, and water waves. It describes the change in frequency or wavelength of a wave as the source or observer is in motion relative to each other.
Does the Doppler Effect occur when both the source and observer are moving at the same velocity?
No, the Doppler Effect occurs when there is relative motion between the source of the wave and the observer. If both the source and the observer are moving at the same velocity, there won't be any change in the observed frequency of the wave.
Why doesn't the Doppler shift appear when an observer moves toward the source?
Doppler's effect does not happen when the observer is moving towards the source because unlike the source when observer moves forward the waves are not compressed and they pass the observer without being compressed and since the doppler effect is due to the Change in wavelength of the wave, it fails to occur.
How can you use Doppler shift in a sentence?
Doppler shift is the change in frequency of a wave that seems to occur as it moves. Scientists study the doppler shift to see whether stars are moving away from or toward our galaxy.
Does the Doppler effect occur when only some types of waves or all types of waves?
It is typical of all waves.
What is the Doppler effect on sound?
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.
