Energy moves from source to receiver in a wave motion. This energy can be carried through various mediums, such as air for sound waves or space for light waves.
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.
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.

the motion of a wave changes when it moves
When a wave moves toward the receiver, the wave frequency remains constant, but the wave speed can change. The frequency of a wave depends on its source and is not affected by the motion of the source or receiver.
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.
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.
A source vibrating with simple harmonic motion produces a sinusoidal wave.
The phenomenon you are referring to is known as the Doppler effect. It describes the change in frequency (or wavelength) of a wave as a result of the relative motion between the source of the wave and the observer.
