Sound of Guitar

Classical Mechanics Level 2

A guitar is a popular musical instrument that makes sound by the playing of its (typically) six strings with the sound being projected either acoustically or through electrical amplification. The above shows the profile of a classical guitar which is typically played by strumming or plucking the strings with the right hand while fretting the strings with the left hand. Which of the following statements is NOT correct when we strum one of the strings?

a) The string makes standing waves.
b) The shorter the string, the higher the sound.
c) If two string have the same length, then the thicker string makes a higher sound than the thinner string.

a) only b) only c) only none of them

it is because heavy string is not easily vibrated and is damped

It is one of the properties of string that the thinner the string the more frequency and more sound than the thicker string.So when the string is thin it will make more sound.It is a fundamental property of sound.

A) Please ignore the fact that i lack of knowledge about "Standing Waves"

B) The shorter the string, the higher pitch it is. This is known through experience with a violin or a guitar, when we press on the frets, we are actually shortening the strings so that they produce tones of higher pitch.

C) At the same length and tension, strings with different thickness actually produce different tones, where thin strings produce higher pitches and thicker strings produce lower pitches.

As a musician, the answer is very instinctively =)
