It means the air moves back and forth 70 times in one second. These vibrations in the air are what we perceive as sound.
I think you mean pitch.
The pitch of a sound is determined by its frequency. A high-pitched sound has a higher frequency, while a low-pitched sound has a lower frequency. The unit of measurement for frequency is hertz (Hz).
The definition of sound is : "Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear." Sound can be measured by amplitude (loudness) and pitch (The frequency of the vibrations). Therefore sound does not affect frequency but frequency affects the pitch of the sound.
No, the speed of sound is not independent of frequency. In general, the speed of sound increases with increasing frequency. This relationship is due to the way sound waves travel through a medium, such as air or water.
To find the frequency, use the formula: frequency = speed of sound / wavelength. Assuming the speed of sound is 343 m/s, the frequency of the sound wave would be approximately 229 Hz. Yes, this frequency is within the audible range for humans, so you would be able to hear this sound.
Does what hurt? Do you mean sound?
I think you mean pitch.
The pitch of a sound means the frequency. That stays constant with distance. You mean the sound pressure level that decreases with distance.
The pitch of a sound is determined by its frequency. A high-pitched sound has a higher frequency, while a low-pitched sound has a lower frequency. The unit of measurement for frequency is hertz (Hz).
The pitch of a sound is determined by the frequency of its vibrations. A higher frequency produces a higher pitch sound, while a lower frequency produces a lower pitch sound.
It is the frequency of a sound that determines its pitch. The higher the frequency, the higher the pitch.
frequency is the pitch of a sound
An echo can be either a high or low frequency sound, depending on the original sound that it reflects. The frequency of an echo is typically the same as the frequency of the original sound wave.
Harmonics are multiples of the fundamental frequency of the wave.
I think you mean its frequency, which is commonly described as its pitch
The pitch of sound is most closely related to its frequency. A higher frequency sound wave produces a higher pitch sound, while a lower frequency sound wave produces a lower pitch sound.
No, the loudness of a sound is related to its intensity, which is determined by the energy of the sound wave. Frequency refers to the number of vibrations per second and is perceived as pitch. In general, higher frequency sounds are perceived as more "sharp" or "high-pitched," but this does not necessarily mean they are louder.
