What is the effect in the change in wave frequency caused by the motion of the source of the wave?
Austrian physicist Christian Johann Doppler (1803-1853)discovered that a wave's frequency changes when the source and observer are in motion relative to one another. This is known as the Doppler effect.
The apparent breaking in two of a pencil that is placed diaginally partway into water is caused by?
refraction
Frequency increases as the source approaches an observer and decreases as it recedes?
Doppler effect is a change in frequency and wavelength of a wave. It is caused by the change in distance between the thing creating the wave (causer) and whatever is measuring (watcher), seeing or hearing the wave.Another word for "causer" is "sender". Another word for "change in distance" is "speed".(taken from simple wikipedia).
What is the definition of Doppler effect?
That refers to a change in frequency in light, sound, or some other wave, from the point of view of an observer, caused by a relative movement between the source and the observer. In other words, the source of a wave moves towards us, or away from us. For more details, I suggest you consult the Wikipedia article on "Doppler effect", or some other similar source.
What causes light to be shifted?
It is the Doppler effect and is caused by the light source or the observer moving towards or away from each other. In basic terms, if the two are moving toward each other then the light waves arrive at the observer more closely packed than when they left the source. That is, the wavelength is shorter and the light becomes shifted towards the blue end of the spectrum. If the two source and observer are moving apart then you get a red shift.This is analogous to the pitch of a siren which drops as the vehicle passes you and starts receding from you.

What is a parallax error?
Parallax, more accurately motion parallax, is the change of angular position of two observations of a single object relative to each other as seen by an observer, caused by the motion of the observer. Simply put, it is the apparent shift of an object against a fixed background that is caused by a change in the observer's position.
The apparent shift in wind direction that is caused by the earth's rotation is called?
The Coriolis effect
The apparent shift in wind direction that is caused by the earths rotation is called the?
Coriolis effect
Mental retardation caused by what disorders is often apparent from infancy?
If retardation is caused by chromosomal or other genetic disorders, it is often apparent from infancy.
What is the apparent rise in the earth's temperature that scientists believe is caused by an increase in the amount of carbon dioxide and other gases in the air?
A:The apparent rise in the earth's temperature is called global warming.
The apparent path of the stars over the course of a single night is caused by?
It is caused by the earth's rotation.
What is the redshift star?
The redshift is caused by relative motion that increases the distance from the source to the observer. The faster the source of light is moving away to the observer, the greater the redshift
What is ischaemic foci?
Ishcaemic foci are also called lacunar infarcts. They are caused when blood flow is interrupted to small areas of the brain. It can be detected by an MRI scan.
What is the apparent force on the wind that is caused by the spin of the earth?
coriolis force
What is the effect in the change in wave frequency caused by the motion of the source of the wave?
Austrian physicist Christian Johann Doppler (1803-1853)discovered that a wave's frequency changes when the source and observer are in motion relative to one another. This is known as the Doppler effect.
