I think you mean pitch.

Why car making high frequency sound when accerelating?
The answer is essentially in the question. Sound is the sensation caused by vibrations in the air. The faster the vibrations, the higher the frequency. So, when an engine is revved, the frequency of the vibrations it creates increases, and it gives higher frequency sounds, perceived as an increase in pitch.
Is it possible to move a source of sound relative to a stationary observer so that there is no shift in the frequency of the sound?
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
Do high frequency sound waves have a higher or lower pitch than low frequency sound wave?
Yes! All sound waves, regardless of pitch move at the same speed provided they are in the same medium. Differences in frequency cause the sound to be perceived as higher or lower. A high pitched sound has a higher frequency and shorter wavelength while low pitched sounds have lower frequencies and longer wavelengths
Does visible light waves have pitch?
no You might say that, even though nobody else ever does. A change in the frequency of sound is perceived as a different 'pitch'. A change in the frequency of light is perceived as a different 'color'. In each case, even a small change in frequency is easily perceptible to the human sensory system. Who cares what word you use to describe it !
What happens when you increase the frequency of a sound wave?
Speed = distance / time [m /s]likewise:Speed of wave = wavelength x frequency [m /s]Since sound waves travel at a fixed speed through a medium* a drop in frequency must cause a corresponding increase in wavelength*Not always true. In water of example, lower frequency waves travel faster than higher frequency waves. When this happens the waves are said to be travelling through a dispersive medium.
When both source and listener move in the same direction with a velocity equal to half the velocity of sound the change in frequency of the sound as detected by the listener is?
If there is no relative velocity between source and listener, there will be no change in frequency.
How does perceived pitch change as a sound source passes a listener?
The perceived pitch of the sound drops (frequency decreases) as the source transitions from approaching the listener to receding from the listener. The phenomenon is called the "Doppler shift", after the German Physicist who explained it and worked out the math.

What is the relative highness lowness or sameness of sound?
The relative highness or lowness of sound is referred to as pitch. Sounds with higher frequencies are perceived as higher-pitched, while sounds with lower frequencies are perceived as lower-pitched. Sounds with the same frequency are perceived as having the same pitch.
Is the perceived frequency of a sound wave?
Pitch
Relationship between period and amplitude of a wave?
The amplitude of a sound is not related to its frequency (wavelength).There might appear to be a connection if the listener's hearing is more or less sensitive to certain frequencies. For example, as a sound with constant amplitude rises in frequency toward the upper limit of the listener's hearing range, it will be perceived as if its amplitude (loudness) is dropping, although that sensation is in the ear of the beholder and not a property of the sound itself.
How is frequency of sound waves related to its time period?
No. The amplitude of a sound is not related to its frequency (wavelength).There might appear to be a connection if the listener's hearing is more or less sensitive to certain frequencies. For example, as a sound with constant amplitude rises in frequency toward the upper limit of the listener's hearing range, it will be perceived as if its amplitude (loudness) is dropping, although that sensation is in the ear of the beholder and not a property of the sound itself.
When a listener moves towards a stationary source the pitch of sound increase why?
Yes, the frequency is higher - same as if the moving source was towards a stationary person -it is all relative
Why does the frequency of sound waves change for a listener when the sound source moves towards or away from the listener?
This is an example of the Doppler effect. Sound is composed of waves. A particular vibration produces a sound wave with a particular wavelength. When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency. When the sound source moves away the opposite happens. The frequency of the sound waves decreases.
