Understanding Loop Formation in a Plucked String

I have a question regarding the formation of loops when a string is plucked at different fractional lengths. In a book I referenced, it is stated that plucking a string at 1/6 of its length produces 3 ...

A conceptual question about waves

If the tension in a string with fixed ends is slightly increased then does the wavelength of a wave travelling along the string change, or does only the frequency change?

How does a string thickness affect the frequency of its harmonics?

The harmonics of a theoretically infinitely small diameter string are pure integer multiples of the fundamental frequency. However, a real string has a thickness, and when vibrating in a harmonic, 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 ...

What happens with natural frequency on a rope which length is changing?

I was watching violin concerto, and I thought of two scenarios of sliding on the string and taking finger off the string as shown in the image: Define $v = \sqrt{\frac{T}{\mu}} = f\lambda$, $T, \mu, ...

How to create a standing wave that doesn't oscillate with the fundamental frequency?

Is there a way to make the string on my violin vibrate in an overtone frequency instead of the fundamental frequency?

Tension in a violin string

Say we have a string of fixed size on a violin. If I were to play it open (without pressing down on it) it would vibrate at a certain frequency. If I were to play it whilst pressing down on the middle,...

Can the wavelength of the standing wave be different from the wavelength of the sound it emits?

I have a question about standing waves on strings. I'll try to explain the best I can, I searched and researched the whole day yesterday but I am confused still: Every frequency has a single, and ...

How can I calculate the number of nodes on a plucked string?

Given the length of the guitar string, can you predict the number of nodes that would exist on that string? My textbook says that there are an infinite number of harmonics that can be created when a ...

Sound of string in a guitar

I study about waves and I learn that the velocity of a transverse wave in a string depends only on the tension and the density of the string. The frequency depends only on the source (whatever ...

What exactly happens, step by step, in string harmonics?

I know that a string when plucked shows harmonics but I do not really understand how. Like, I understand resonating air column and how standing waves are formed there, but I can't seem to get the step ...

How is length of string and frequency of sound related in musical instruments like guitar, violin etc? Also differentiate between note and tone

I read a sentence that a guitarist set his strings before performance then he is changing frequency of sound. I was wondering in which case frequency will be more, if length of string is large or ...

Is the frequency of a vibrating string equal to the frequency of the sound it creates?

Is the frequency of a vibrating string equal to the frequency of the sound it creates? For example, if a string is vibrating at 440Hz, would the sound it creates be 440Hz as well? Furthermore, would a ...

Question about fundamental frequencies

For a string fixed at both ends, with a fundamental frequency of 440Hz, can there be a harmonic when a wave of frequency 220Hz is sent across the string? my book says no, but I disagree; can't ...

When vibrating a string, how exactly is the vibration inverted to create an identical wave traveling in the opposite direction?

I am currently trying to understand standing waves. The key to the phenomenon is that: $$A\sin(kx+\omega t) + A\sin(kx-\omega t)=2A\sin(kx)\cos(\omega t)$$ The shape of $2A\sin(kx)\cos(\omega t)$ is ...
