Solving the Violin String Problem: Frequency, Wave, and Tension

AI Thread Summary
The discussion revolves around solving a physics problem related to a violin string with a mass of 35g and a length of 60cm, vibrating at a frequency of 196Hz. Key questions include determining the frequency change when the string is fingered at 15cm, calculating the wave propagation speed, and finding the string's tension. Participants express confusion about how to apply the relevant equations, such as the wave speed formula and the relationship between tension and frequency. There is uncertainty about the necessary information to solve the problem effectively. Overall, the thread highlights the challenges in applying theoretical concepts to practical scenarios in string physics.

Homework Statement


Mass of violin string = 35g
Length of string = 60cm
Frequency = 196Hz

What is the frequency change to if the string is fingered at 15cm from the top end?
How fast does the wave propagate down the string?
What is the tension in the string?

Homework Equations


v = Squareroot of (Tension Force / (m/L))
vT = wavelength


The Attempt at a Solution


No idea how to approach this problem.. Not enough given information to plug and chug into those equations.

I think the frequency change would be higher? But I'm not sure how to figure out the tension, velocity, or wavelength.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...

Thread 'Rolling without slipping on a curved surface'

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 .
