Yes. The observer would still receive less - or more - wave crests per second.
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.
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.
Yes, the listener will notice the Doppler effect in this scenario. As the listener and the sound source move towards each other, the sound waves in front of the source are compressed, causing a higher frequency that the listener perceives as higher pitched. This change in pitch is due to the relative motion of the source and the listener, leading to the Doppler effect.
The Doppler Effect causes the frequency of sound waves to change when the source of the sound or the listener is in motion. When a sound source is moving towards the listener, the frequency appears higher (higher pitch), and when moving away, the frequency appears lower (lower pitch). This effect is commonly experienced when a car passes by and the pitch of the sound changes.
No, an echo is not an example of the Doppler effect. The Doppler effect occurs when there is a change in frequency of a wave due to the relative motion between the source of the wave and the observer. An echo is created when sound waves reflect off a surface and return to the listener, producing a repeated sound.

The apparent change in the frequency due to motion of the source relative to the listener or vice versa is called Doppler's effect . Uses of Doppler's effect : It is used to compute the velocities of stars relative to earth by noting change in wavelength. It is also used to detect moving objects like aircraft by reflect of the radar waves.
The Doppler Effect.
An Austrian physicist, Christian Doppler, is best known for the effect named after him, the Doppler effect, which he proposed in 1842. It is the change in frequency of a wave as measured by an observer in motion relative to the source of the wave.The Doppler effect (or Doppler shift) is the change in frequency and wavelength of a wave for an observer moving relative to the source of the waves. It is commonly heard when a vehicle sounding a siren approaches, passes and recedes from an observer. The received frequency is increased (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is decreased during the receding motion. The higher or lower frequency alters the pitch of the sound as heard by a stationary listener, making it sound higher-pitched or lower-pitched.
Doppler effect. This phenomenon occurs when the frequency of sound waves shifts due to the motion of the source or the listener, causing a perceived change in pitch.
The Doppler effect is that apparent change of the frequency of a moving object when someone is stationary. A car may seem to get louder as it gets closer to a person and then the sound will drop as the car gets away.
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.
The change in frequency of a sound due to motion of the source is called the Doppler effect. If the source is moving towards the observer, the frequency of the sound appears higher (blueshifted), while if the source is moving away, the frequency appears lower (redshifted). This effect is commonly experienced with passing vehicles and sirens.
