Unfingered Guitar String Vibration Frequency: 627 Hz

AI Thread Summary
When a guitar string vibrates unfingered, it produces a frequency of 627 Hz. When fingered one third of the way from the end, only two thirds of the string vibrates, affecting the frequency. The solution involves understanding string harmonics and the relationship between string length and fundamental frequency. An initial calculation suggested a frequency of 940.5 Hz, but further review of course literature is recommended to clarify the correct approach. Understanding these concepts is crucial for accurately determining the new frequency produced by the fingered string.

Homework Statement


When unfingered, a string on a guitar vibrates at 627 Hz.

What frequency will the string produce when fingered one third of the way from the end, that is only two thirds of the string can vibrate?

I have solved the answer by relating to the string harmonics. (627Hz*0.5)+627Hz= 940.5Hz

Then you might want to take another look in your course literature on the subject and think about how the length of the string relates to the fundamental frequency.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
