How is the Doppler affect used to find the speeds of moving objects?
Wiki User
∙ 8y ago
The Doppler effect is used by measuring the change in frequency of waves, such as sound or light, emitted or reflected by a moving object. By comparing the observed frequency with the emitted frequency, the speed of the object towards or away from the observer can be calculated.

How does air resistance affect moving objects?
Air resistance acts as a drag force that slows down the motion of moving objects by pushing against their direction of movement. The magnitude of the air resistance force depends on the object's shape, size, and speed. Objects with larger surface areas and faster speeds will experience greater air resistance, causing them to slow down more quickly.
What is the apparent deflection of an object caused by the apparently acts on moving objects?
The apparent deflection of an object caused by the Coriolis force is due to the Earth's rotation, which makes moving objects appear to curve. This deflection is more pronounced for objects moving over long distances or at high speeds, such as atmospheric currents or ocean currents, but is generally negligible for everyday objects.
What is the word that causes all objects to fall at different speeds?
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
If blank is the frame of reference Earth and everything on it is moving?
If Earth is the frame of reference, then everything on it is moving relative to Earth. Objects on Earth may be moving in different directions and at different speeds, depending on their location and motion.
What term describe an apparent change in frequency of sound waves of rapidly moving?
Doppler effect describes the apparent change in frequency of sound waves as a source moves relative to an observer.

Why the planets seemed to move at different speeds?
The gravitational pull of other objects in space affect all
How does air resistance affect the velocity of falling objects?
Slows an object down or speeds one up.
What size does an object have to be in order to view an observable red shift from a distant object in space?
Objects must be very large and moving at high speeds relative to an observer in order for their light to exhibit a measurable red shift due to the Doppler effect. This is commonly observed in astronomical objects such as galaxies and quasars located far away from us in space.

What does EMc2 mean in spanish?
This is not Spanish, this is the equation that describes the behavior of objects moving at speeds comparable with the speed of Light: E = M c2

What is the fastest moving object in sports?
A cricket ball bowled by a fast bowler is considered one of the fastest moving objects in sports, reaching speeds over 90-100 mph.
As you drive down the road in a car why objects inside the car appearto be stationary when compared to the objects outside of the car?
When you are driving, the objects inside the car are moving at the same speed and direction as the car, so they appear stationary relative to you. On the other hand, the objects outside the car are stationary or moving at varying speeds, which creates a visual contrast making them seem like they are moving relative to you.
What term describe an apparent change in frequency of sound waves of rapidly moving?
Doppler effect describes the apparent change in frequency of sound waves as a source moves relative to an observer.
Is subsonic speed underwater?
Subsonic speed refers to speeds below the speed of sound in a medium. In water, the speed of sound is higher than in air, so typical speeds of objects moving through water are considered subsonic.
