The Doppler effect is that apparent change of the frequency of a moving object when someone is stationary. A car may seem to get louder as it gets closer to a person and then the sound will drop as the car gets away.

∙ 9y agoThe apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler Effect. As the object moves closer to the observer, each wave takes less time to reach him or her than the previous one, reducing the interval between each and increasing their apparent frequency.

cause and worked out the math that relates the shift to the relative speed.

What is the Planck-Einstein equation?
The relation between the energy (E) of a photon and the frequency (v) of its associated electromagnetic wave is called the Planck relation or the Planck--Einstein equation:E = hvh is the Planck constant which as a value of about 6.626 * 10-34 J*s (a very very small number)

How does perceived pitch change as a sound source passes a listener?
The perceived pitch of the sound drops (frequency decreases) as the source transitions from approaching the listener to receding from the listener. The phenomenon is called the "Doppler shift", after the German Physicist who explained it and worked out the math.

What is an apparent change in frequency of a sound source that moves relative to an observer?
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
How Doppler effect?
The apparent change in the frequency due to motion of the source relative to the listener or vice versa is called Doppler's effect . Uses of Doppler's effect : It is used to compute the velocities of stars relative to earth by noting change in wavelength. It is also used to detect moving objects like aircraft by reflect of the radar waves.

A relation on father's side is called?
A relation on your father's side of your family is called a paternal relation.
Does an ambulance siren's pitch really change - what if the ambulance was stationary?
Modern electronic sirens change amplitude and pitch. Older sirens produced tones that changed in amplitude (volume) but were changed in pitch by their motion relative to the listener: increasing in frequency as they approached and decreasing in frequency when they moved away. This is called the Doppler Effect.
What is the ratio of a frequency to its total frequency?
The ration of a frequency to its total frequency is called relative frequency.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
