I thought about it and I think I should phrase it...why are the first and fourth modes always the ones that get excited.

Ahh I can see this a lot clearer now, your posts are very insightful, thank you. The time that it takes to complete one cycle of stick and slip will either produce constructive or destructive interference of the waves in the cord, or some combination of the two...I think. Also I did Fourier...

The driving force is actually caused by "stick and slip" of a 0.2Kg sled on a surface. The sled is connected to a load cell with a string and the surface moves under the sled, and the cell basically measures the tension in the string. The load cell samples the tension at 800measurements/second...

I did Fourier analysis on a set of force data from a vibrating string. In my graph of magnitute and frequency, I'm getting major peaks at 62.1 Hz and 249.0 Hz. There is a tiny blip in the data at 125 Hz and nothing at 186 Hz. I have two questions. Do the peaks at 62.1 and 249 mean that those...

In the case of the quantum eraser experiment, how do the idler photons "know" if they are falling on 2 separate detectors that can distinguish the slit that their partner photons went through, or falling on one big detector that cannot distinguish the slit, thus producing interference. It seems...

Maybe it's easier to think of a probability density instead of a point particle. So then you can invision a continuous smooth shift in the most likely place for the particle to exist, because I guess you can assign an infinite number of points in space with a probability function.

When a paritlce moves from A -> B is its motion broken into finitely many small jumps as I think the OP is suggesting, or is the motion more accurately described as a smooth transition with no possible way to break it down into steps? Is there/Has there been a way to prove this theoretically...

Okay, they are each other. Why are the forms of pure energy and pure mass related by c^2?

Im a 3rd year physics major. I understand the equation E=mc^{2}. But i don't understand why mass and energy are related by the number c. How are mass, energy, and the speed of light so inextricably related that we can describe their relationship with one simple equation?

Haha Phys 400? I am having similar trouble...
