What frequency of cord shaking maintains the same vertical motion for a point on the cord after increasing the wave speed on the cord?

It's not specified which point on the cord we are focusing on. That is for good reason: different points behave the same way, just with a different phase offset, which is not relevant to the question. ...

What frequency of cord shaking maintains the same vertical motion for a point on the cord after increasing the wave speed on the cord?

You already have a nice, brief and concise answer but I'd like to add more to it. From the "fundamental" equation for waves $$c = \lambda f \tag{1}\label{1}$$ where $c$ is the speed of wave ...

Is there any end to the electromagnetic spectrum?

In theory, the electromagnetic spectrum should extend indefinitely without limit. You can create an electromagnetic wave with arbitrarily long or short wavelength, and therefore arbitrarily low or ...

Are gamma rays the limit of the frequency photons can attain, and if yes, why?

Which Universal factor imposes this limit of electromagnetic radiation, and what is it called? In the table here for the electromagnetic spectrum the energy of a gamma rays is given in megahertz ...

What frequency of cord shaking maintains the same vertical motion for a point on the cord after increasing the wave speed on the cord?

Since this is a $y$ vs. $t$ graph, the frequency of the wave can easily be picked out as the (inverse) time between matching parts on the wave (e.g. peak to peak, $0$ to $0$, trough to trough, etc.). ...

Frequency and length

When making a sound with an instrument, what you hear is the base frequency and higher harmonic frequencies which have increasing frequencies. The frequencies of the higher harmonic frequencies are ...

Can Low-Freq sound wave with High-Amplitude destroys human ear?

If my understanding of the biology is correct, ears are destroyed when the difference of the pressure on the different sides of the eardrum is sufficiently large. If someone were not able to equalize ...

How can you change the resonant frequency of a solid guitar body?

Yes, the resonant frequency of a solid guitar body can be changed by adding or removing material but it provides no benefit to the sound that can't be accomplished by less destructive means such as ...

Why can we hear instruments but not voices?

If you look at the graph, you will see that the green area depicts the entire "auditory experience". In other words, anything in that area will be experienced as sound. Outside that, you may ...

Why can we hear instruments but not voices?

What’s the source of that graph? I’m guessing that the two inner loops correspond to which sounds can be produced, not which can be heard.

Are gamma rays the limit of the frequency photons can attain, and if yes, why?

Gamma rays doesn't impose any frequency limit as per definition, because gamma rays just means electromagnetic waves which have frequency $\gt 10^{18}~\text{Hz}$. Upper frequency limit is imposed by ...

What frequency of cord shaking maintains the same vertical motion for a point on the cord after increasing the wave speed on the cord?

Bottom line intuitive answer: Changing the propagation speed affects the relationship between frequency and wavelength. The wave moves faster, but is correspondingly longer, and those two cancel out,...

How to calculate the overall harmonics of a system of tubes?

Summary: There is not a simple way to obtain the fundamental frequency of the composite tube you are describing in any sort of accurate manner. A more rigorous approach is necessary. Longer ...

Does air column change its frequency to one of its modes as and when needed?

Changing the length of the column means that this is a different system than what you had before (or the same system with different characteristics if you prefer that way of thinking). The simple ...
