Observer drift is when two people who are observing something start agreeing with each other more and more often. For instance, if two teachers are rating final projects, and one of them rates more strictly than the other and they both know that, then the strict one might start thinking that he or she is too strict and the easy one might think he or she is not strict enough, and so they will change the way they rate things to be more similar. In teaching, sometimes this is a good thing, because you get more consistent grades, but in Psychology, where a lot depends on the observer being unbiased, it is usually a bad thing because it tends to sway the results one way or another and corrupt the results of an experiment.
Yes, time for an object in motion relative to a stationary observer appears to pass slower.
when position of the body with respect to an observer change with time then the body are said to be in motion.
The apparent motion of an object can vary depending on the motion of the observer. This is due to the concept of relative motion, where the perception of an object's movement is influenced by the observer's own motion. For example, if the observer is moving towards an object, the object may appear to move faster than if the observer is stationary.
An observer uses a frame of reference to detect motion because motion is relative and depends on the observer's point of view. By using a frame of reference, the observer can establish a stationary point against which to measure an object's position and velocity. This helps in determining whether an object is in motion or at rest relative to the observer.
Yes, the frequency of a wave changes if the observer is moving relative to the source of the wave. This is described by the Doppler effect, where the frequency appears higher if the observer is moving towards the source, and lower if the observer is moving away from the source.
