How Are Standing Sound Waves Solved?

AI Thread Summary
The discussion focuses on the calculation of standing sound waves, particularly the relationship between frequency and wave velocity. It highlights that while the velocity of sound differs in air and string, the specific value may not be crucial since most variables will cancel out in the equations. The conversation also touches on the formula for frequency, emphasizing that if F1 equals 440 Hz, it can be expressed in terms of another frequency, F2, with a constant multiplier. Ultimately, the key takeaway is that the length of the medium is the primary unknown in the calculations. Understanding these relationships simplifies the process of solving for standing sound waves.

Solved it. Thanks anyway.

Wait, how do you know the velocity of the wave? Doesn't that only work for a wave in air? Shouldn't you use a different value for the velocity on a string?

EDIT: It really doesn't matter, though. Everything but the length and frequency will cancel.

So if F = 440hz, then F1 = 440hz = xF2 = x(523hz), right? Where x is some constant to get 440 (don't want to calculate it =/ )

So then F1 = m(v/(2*30)) = xm(v/(2*L))

You know everything but L by now and everything else cancels.

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

Thread 'A bead-mass oscillatory system problem'

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
