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 perceived pitch of a sound to change based on the relative motion between the source of the sound waves and the listener.
Pitch is not affected by the relative motion of an object. The pitch of a sound is determined by the frequency of the sound wave, which remains constant regardless of the object's motion.
Both. The Doppler effect occurs when there is relative motion between the sound source and the listener. If either the source or the listener is in motion, it will cause a shift in the frequency of the sound waves that are perceived.
No, if the source and receiver are stationary and only the air is moving, there will be no change in the frequency or wavelength of the sound. The Doppler effect occurs when either the source or the receiver (or both) is in motion relative to the medium through which the sound is traveling.
The Doppler effect is the change in frequency of sound waves as a sound source or listener moves relative to each other. When a source is moving towards a listener, the frequency appears higher (shorter wavelength) due to compression of waves. When moving away, the frequency seems lower (longer wavelength) due to stretching of waves.

as the motorcycle approaches the observer, the frequency increases.

The apparent change in frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler effect. This effect causes the perceived frequency of the sound to change depending on the relative motion of the source and the observer – it is higher as the source approaches the observer and lower as it moves away.
No, the wave speed does not change in the Doppler effect. The apparent frequency and wavelength of the wave change due to the motion of the source or observer relative to the wave, but the speed of the wave remains constant.
The apparent change in frequency of waves is known as the Doppler effect. It occurs when there is relative motion between the source of the waves and the observer, causing a shift in the perceived frequency of the waves. This effect is commonly observed with sound waves and light waves.
The Doppler effect in sound is symmetric. This means that whether the source is moving towards the observer or away from them, the effect on the frequency of the sound is the same. The change in frequency depends on the relative motion between the source and the observer, not the direction of that motion.
The Doppler effect causes a change in sound because of the relative motion between the source of the sound and the observer. When the source is moving towards the observer, the sound waves are compressed, leading to a higher frequency (higher pitch). When the source is moving away, the sound waves are stretched, resulting in a lower frequency (lower pitch).
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.
