when a man closes the holes near the mouth of the flute, will the pitch of the sound increase or decrease?
Answers
answer : increase
explanation : pitch of sound depends on frequency of it. pitch of sound is directly proportional to frequency. means, pitch of sound increases when we increase frequency of the sound.
here when a man closes the holes near the mouth of the flute , wavelength of wave decreases. we know, wavelength is inversely proportional to frequency. so, frequency increases. and hence, pitch of sound increases.
The pitch of the sound will decrease.
The reason for the above answer is that as the hole near the mouth of the flute will be covered, so the air breathed from the mouth of the flute will take more time to be released out of the flute.
As the nearest hole will be closed, the air will have to pass out from the holes situated in the middle or at the far end of the flute, which will increase the time and hence decrease the pitch of it.
A flute has several holes in it which let the air pass through them, controlling the music created through the air breathed into it.
