The wavelength of a transverse wave is the distance between successive crests.
Just the imparted energy. As with water or electrons in a wire the energy moves and the medium stays in its local area.
Just the disturbance produced at one point gets transferred to other locations. ie from source to the receiver. In case of mechanical wave, such as sound, the push and pull would be quickly transferred through the material medium. But in case of electromagnetic wave, such as light even through free space ie vacuum, the electrical and magnetic disturbances are quickly transmitted.
As a wave source moves towards an observer, the pitch of the wave increases. This is known as a Doppler shift, where the frequency of the wave appears higher due to the relative motion between the source and the observer. Conversely, as the source moves away from the observer, the pitch of the wave decreases.
frequency and pitch would change as the source moves. As the source moves away, the frequency and pitch decrease, and as the source moves closer, they increase. This is due to the Doppler effect, where the relative motion between the source and observer causes a shift in frequency.
A source vibrating with simple harmonic motion produces a sinusoidal wave.

the motion of a wave changes when it moves
The speed of a radio wave is constant and is just under the speed of light at 300^6 metres per second whether the signal is travelling toward or away from the reciever. What I think you are asking is about Doppler shift in which case a receiver travelling towards the emitter or visa versa would experience the compression of radio waves and therefore a frequency shift to a higher frequency and when travelling away the wave would be elongated which would result in a lower frequency signal.
a sweeping motion
frequency and pitch would change as the source moves. As the source moves away, the frequency and pitch decrease, and as the source moves closer, they increase. This is due to the Doppler effect, where the relative motion between the source and observer causes a shift in frequency.
A source vibrating with simple harmonic motion produces a sinusoidal wave.
A wave barrier is produced when a wave source moves faster than the waves it creates, causing the waves to pile up in front of the source. This creates a barrier of high wave intensity.
The Doppler effect causes a shift in frequency or wavelength of a wave when there is relative motion between the source of the wave and the observer. This effect is commonly observed with sound waves, where the pitch of a sound appears higher as the source moves toward the observer and lower as the source moves away.
