For me, the rubber band didn't stretch permanently. You just don't want too much tension on it. And yes, putting something will create a node and change the wavelength of the standing wave.

Wow, this brings back memories. I ended up using a rubber band and my EE turned out to pretty good, got an A. My final graph was F^2/T against T, and I ended up with an interesting graph that was linear at a limited interval. If you are thinking of using a guitar string, then you can...

Thank you so much for your help! But I don't have much time and resources, it's a high school essay after all, and want to continue with a rubber band, while acknowledging the limitations. I did some research and found out a method to make the rubber band behave closely to a spring...

Thank you, but that's not really the problem now. Since the rubber band does not exactly follow the Hooke's law, I'm not necessarily sure of how valid my theory is. I did some research and found out a method to make the rubber band behave closely to a spring. Since this is not a major part of my...

I have an extended essay for the IB diploma in physics, where my research question is: How does the tension of a rubber band affect the frequency of the standing wave when plucked? The relationship/theory I want to explore is stated above. It starts off with the Mersenne's law, but I try to...

Do you know any string-like material that obeys the Hooke's law but also stretches noticeably with tension?

The definition of the Hooke's law states: a law stating that the strain in a solid is proportional to the applied stress within the elastic limit of that solid. The Hooke's law is not limited only to springs, but strings including a rubber band also follow the law

Alright, so the Mersenne's laws can be used to describe the relationship between tension and frequency: f=sqrt (T/u)/2L The relationship states that frequency is directly proportional to the square of tension. What I want to show in my research essay is that this is not necessarily the case...

I derived a relationship between frequency and tension of a string, accounting for tension's effect in the linear density of the string. So in a nutshell, the equation is more complicated and is in the form of f^2=aT^2+bT (f is frequency, T is tension, ab are constants involving the control...

Thanks guys, I got the frequency coutner by cateater on the app store (some of the android apps are not on the app stores). Nonetheless, it seems to be working pretty well.

Alright, I decided to use a rubber band instead of a violin string, as it is too hard to prove experimentally the effect of the spring constant on the frequency, the effect is about 1-2Hz. So I will do two experiments 1. getting the spring constant k of a rubber band and 2. getting the...

Alright, thank you!

I'm only looking to obtain the fundamental frequency of the sound produced and not its overtones. And on the resolution, having thought about it, I don't mind too much on the resolution of the device, something along the lines of ±5Hz would be nice.

I need an instrument to measure the frequency of the sound of a vibrating violin string for a high school research essay. I tried using a Labquest and a vernier microphone to measure but it was way too imprecise. I need the instrument to very accurate in measuring Hz as the nature of my essay...

1. The problem statement, all variables, and given/known data So I'm doing an IB extended essay on the relationship between frequency and tension of a violin string. As you apply more tension to the string (using weights and pulley), the frequency will be higher, as shown below. There's not too...
