Why are SHM formulas applicable to waves on strings? Are they applicable for all transverse waves?
This is a very basic and conceptual doubt, I am in high school, they have taught us SHM formulas in school and told us to apply it on waves on strings, but I had a problem connecting the dots and in ...

Mechanism of Guitar String Tuning: Tension, Length, and Material Properties
I'm trying to understand the precise physical mechanism involved when tuning a guitar string, specifically from the perspective of the string's tension.
When we turn the tuning pegs, we intuitively ...

Is this Y-shaped pendulum equivalent to this single pendulum?
As shown below, a mass point is suspended by two ropes of the same length. The mass can swing back and forth (into and out of your screen if looking at this picture) slightly, forming a pendulum. If ...

Height of a mass swinging on a rope
The adjoint figure shows blocks of masses (assumed identical) rotating in a circle and they are binded by strings. We can see that the angle of inclination is increasing as we are moving to the left. ...

How does a guitar string produce sound?
I'm curious about the mechanism of a guitar producing sound. Of course, I know once a string is plucked it vibrates in a superposition of several harmonics, but what I don't know is what happens next. ...

Why the rope doesn't slack in the simple gravity pendulum?
One day I study the simple gravity pendulum, which an angle is less than $\frac {π}{2}$.
It doesn't consider friction and air drag.
In the simple gravity pendulum, My textbook says ”assume the rope ...

Oscillation of Free End of String (Waves)
Suppose a wave pulse is produced in a string clamped at one end, and the other end is loose(tied with a massless ring which can move along a vertical rod, there's no friction). Now, I have searched ...

What shape will two independent pendulums draw?
At an art exhibition I saw a piece that looks like this:
There are two independent rod pendulums each with an equal mass $m$ at the end. One pendulum has a blank piece of paper attached to it. The ...

Natural Harmonics on a String
Consider the Dirichlet boundary value problem of a guitar string stretched between two fixed points which is made to oscillate by pinching and releasing the string.
It can be shown in quite ...

Why do guitar strings behave so nicely?
To explain the harmonics on a guitar string, we use 2D models of the string. For example we assume that the string can only go up and down. But the string is inherently a 3D object and it could ...

What kind of motion will a string behave when the condition to form stationary waves is not met?
We know that stationary waves can only form when the wavelength of the wave and the length of the string satisfies certain conditions.
My question is, how will the string behave when this condition is ...

Why does the classic wave equation for a non-relativistic string look like the Klein-Gordon equation?
There is a very old equation known as the "wave equation". It's an ordinary classical non-relativistic differential equation which applies to just about every kind of ordinary wave you can ...

Is there a relation between eigenvector and amplitude for a beaded string
I have a string fixed at both end with 5 beads.
At $$t=0$$ $$v_p=0$$ where $p$ is the index for each bead and their initial displacement are $$(3,0,\sqrt{3},2,2)$$ I have to find the amplitude for the ...

Why we want the string to be massless in the ideal model of simple pendulum?
I couldn't think about a reason why the string must be massless. Wouldn't the assumption that the air resistance is negligible, the angle $\theta$ is small and the string is non-stretchable suffice ...
