short answer it doesn't. however with external forces acting on the wave it will diminish over time

The loudness of a sound is a reflection of its?
The "loudness" with which you perceive a sound is determined by -- the amplitude of the sound as it leaves the source -- the distance between you and the source -- obstacles or absorptive media in the path between the source and your ear -- reflective surfaces near the path, leading to multipath interference, constructive or destructive at the frequencies that comprise the sound -- the relative amplitude response of your ear at the frequencies that comprise the sound.
Does Amplitude change frequency?
no...frequency is the property of source....
What distance does sound travel through a solid?
There is no limiting distance. But just like in any other medium, the sound generally spreads out and its amplitude decreases as it proceeds farther, so there's some distance past which you can't detect it any more, and to all appearances, you would say that the sound has not traveled any further than that. The distance depends on the substance, and on the amplitude of the sound at its source. (Sound waves that originate in thunder travel many miles through the ground. Sound waves that originate in earthquakes travel many hundreds, or thousands, of miles through rock.)
What is the amplitude of am waves?
The amplitude is the amount of power the transmitter is putting out depending the signal being fed into it from the source. It varies constantly with the signal. It is called amplitude modulation. Modulation of over %100 can cause the transmitter to send harmonics called band splatter.
What is the size of the shadow and the distance of the object from the light source when a shadow is formed?
If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.

How do you receive small amplitude input from large amplitude source using clamper?
use a clamper and try not to use clipper..
The amplitude of a wave from a point source decreases as the inverse square of the distance fron the source?
yes... its true...the inverse square law is universal. it can be applied to gravity between two objects, the electric force between 2 charges etc...

How is pitch and volume affected by the speed or location of an object?
The volume (amplitude) of a signal emitted by an object, as measured by an observer, is inversely proportional to the distance of that object from said observer. Specifically, the volume is subject to the famous 'inverse-square' law, where the amplitude measured at a given distance from the source of the signal will decrease with the square of the distance of the observer from the source.For example, if the amplitude of a signal measured at 1 meter from an object is 8 units, then the amplitude measured at 2 meters (double the distance) will be 2 units (one quarter the amplitude).That is the core relationship between volume and the location of the source.Pitch (frequency) of a signal is affected by the speed of the object relative to the observer. If the source is travelling towards the observer, the pitch (frequency) will be higher than if the source were stationary. Similarly, if the object is travelling away from the observer, the pitch (frequency) will be lower that if the source were stationary. This is known as the Doppler Effect. An increased pitch due to the Doppler Effect is known as Blue Shift and the reduced pitch due to a receding source is known as Red Shift.One can calculate the observed frequency if the emitted frequency and the relative speeds of the source and observer are known as follows:f = ( (V+Vr)/(V+Vs) )F0Where:f is the observed frequencyF0 is the emitted frequencyV is the speed of the signal in the medium (speed of sound, light etc)Vr is the speed of the receiver in the medium (positive if moving towards the source)Vs is the speed of the observer in the medium (positive if moving away from the receiver)
Which supply source changes the polarity constantly?
AC source of electric power changes changes polarity constantly, in amplitude.
