Standing wave
The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It causes the frequency of the wave to appear higher when the source and observer are moving toward each other, and lower when moving away from each other. This effect is commonly observed in situations like the sound of a passing siren.
The wave produced by fans in a stadium is a transverse wave. In a transverse wave, the motion of the medium (the standing and sitting fans) is perpendicular to the direction in which the wave travels. This causes the wave to appear as a "crest and trough" pattern moving across the stadium.
If the source of a wave is moving towards the observer, the observer will perceive a higher frequency (blue shift) in the wave. If the source is moving away, the observer will perceive a lower frequency (red shift) in the wave. This is known as the Doppler effect.
When a wave source is moving towards an observer, the pitch or frequency of the wave increases, known as a Doppler shift. This occurs because the waves are reaching the observer at a faster rate due to the source moving closer. Conversely, when the wave source is moving away from the observer, the pitch or frequency decreases.
Once the wave has left the source that generated it, the frequency can't be changed.If you happen to be moving toward or away from the source at a high enoughspeed, then the frequency of the radiation may appear to you to be changed.But it's not.

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It causes the frequency of the wave to appear higher when the source and observer are moving toward each other, and lower when moving away from each other.

A sine wave.
If the source of a wave is moving towards the observer, the observer will perceive a higher frequency (blue shift) in the wave. If the source is moving away, the observer will perceive a lower frequency (red shift) in the wave. This is known as the Doppler effect.
When a wave source is moving towards an observer, the pitch or frequency of the wave increases, known as a Doppler shift. This occurs because the waves are reaching the observer at a faster rate due to the source moving closer. Conversely, when the wave source is moving away from the observer, the pitch or frequency decreases.
the air molecules
The P-wave which is a form of body wave known as a compression or longitudinal wave.
The energy of a wave moves forward with the wave. A wave is moving energy, and the wave carries it in the direction of propagation.
