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...
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...
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...
