When a source moves toward the Earth its wavelength is shortened, a phenomenon known as blueshift. When a source moves away from the Earth its wavelength is increased, a phenomenon known as redshift.
The maximum distance that pendulum moves away from its position at rest is called the amplitude of oscillation.

When a sound-source moves toward you, its pitch gets higher and the sound gets louder. When it moves away, the pitch lowers and it gets quieter. The frequency change is called the Doppler shift.
The shadow will get longer.
It dims......Nikki
As you move farther away your shadow get bigger and goes away

This is an example of the Doppler effect. Sound is composed of waves. A particular vibration produces a sound wave with a particular wavelength. When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency. When the sound source moves away the opposite happens. The frequency of the sound waves decreases.
It gets colder.

Frequency change when 1)Source moves toward the observer 2)Source moves away from the observer 3)Observer moves toward sourse 4)Observer move away from the sourse, otherthan these observer and sourse moving away or towards each other.
With respect to light, the Doppler effect refers to the apparent change in the frequency (and wavelength) of electromagnetic radiation due to the relative motion of the source relative to the observer. When the source (i.e. a star) moves AWAY from the observer, there is an apparent rarefaction (expansion) in the wavelength of emitted light (i.e. frequency decreases), causing a shift in the emission spectrum towards the red side. This is known as redshifting --> the star is moving away from the observer. The opposite happens in blueshift, when the source moves towards the observer.
