The guitarist shortens the oscillating length of the properly tuned D-string by 0.15 m by pressing on the string with a finger. What is the fundamental frequency, in hertz, of the new tone that is produced when the string is plucked?

The fundamental frequency is "190.52 Hz".

Explanation:

The given question is incomplete, please find attachment of the complete problem.

The given values are:

Frequency,

f = 146.8 Hz

Length of D-string,

L = 0.61

As we know,

⇒

On putting the given values, we get

⇒

⇒      

⇒      

So,

The new length will be:

⇒  

⇒    

⇒    

multiple

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
