To decrease the pitch of a sound, you can lower the frequency of the sound wave by either stretching the material producing the sound (e.g., a guitar string) or slowing down the vibrations of the sound source. This will result in a lower pitch sound.
As the ambulance moves away from you, the pitch of the sound will decrease. This is because the sound waves get stretched out due to the Doppler effect, causing the frequency of the sound waves to decrease as the source moves away.
Decrease in frequency or pitch of the sound, also known as a Doppler shift, resulting in a lower pitch.
As Lorna moves further away from the alarm, the pitch of the sound will decrease. This is because the frequency of the sound wave will become lower as the distance increases, resulting in a lower pitch sound being perceived.
The pitch of a sound wave is directly related to its frequency. Higher frequency waves produce higher pitch sounds, while lower frequency waves produce lower pitch sounds. Pitch is essentially how high or low we perceive a sound to be.
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.

Rising pitch refers to an increase in the frequency of sound waves, making a sound higher in pitch. Falling pitch refers to a decrease in the frequency of sound waves, making a sound lower in pitch. These changes in pitch are perceived by the human ear as variations in tone or melody.

Decrease.
If the pitch of a sound is increased, the frequency of the sound waves also increases. Since the speed of sound remains constant in a given medium, an increase in frequency results in a decrease in wavelength. Thus, a higher pitch corresponds to a shorter wavelength.
The pitch of a sound wave is directly related to its frequency. Higher frequency waves produce higher pitch sounds, while lower frequency waves produce lower pitch sounds. Pitch is essentially how high or low we perceive a sound to be.

When a sound source moves towards you, the pitch will increase (higher frequency) due to a Doppler shift. Conversely, when a sound source moves away from you, the pitch will decrease (lower frequency). This phenomenon is commonly experienced in everyday situations, such as when a vehicle passes by.
The period would decrease, since the period is simply the reciprocal of the frequency. Also, the wavelength should decrease - since the speed of a wave usually doesn't depend significantly on the frequency, and the wavelength is equal to the speed divided by the frequency.
If the wavelength of a sound wave increases, the frequency of the wave decreases. This means that the pitch of the sound would decrease. Essentially, the sound wave becomes stretched out, resulting in a lower pitched sound.
You can alter the pitch of an elastic band when you pluck it by stretching it tighter to increase the pitch or loosening it to decrease the pitch. The tension in the band affects the frequency of vibrations produced, which in turn changes the pitch of the sound.
