Waves -- How does increasing tension affect frequency and period?

AI Thread Summary
Increasing tension in a string generally leads to an increase in frequency, contrary to the observation that frequency decreases with tension in the simulation discussed. The relationship between frequency and tension is more complex when considering different types of waves, such as standing versus progressive waves. For standing waves, frequency increases with tension, while for progressive waves, frequency remains constant regardless of tension. The period (T) is inversely related to frequency (f), meaning as frequency increases, the period decreases. Clarification on the type of wave and simulation settings is essential for accurate interpretation of the results.

How does increasing tension affect frequency and period (T)?

If you pull gut of violin or guitar tighter so with higher tension the scratch sound gets higher pitch so higher frequency. Period T is inverse of its frequency f, T=1/f.

It looks like frequency is decreasing as I increase tension but online it says frequency increases as tension does. Also, I am unsure about what happens to the Period
There is missing information. It is not clear if you are asking about a simple progressive (travelling) wave or a standing (stationary) wave. Also, if you are referring to the simulation, you would need to indicate what settings you used.

Also, you said “It looks like frequency is decreasing as I increase tension”. Even with the missing information I’d guess you have got this wrong - check again!

You said "online it says frequency increases as tension does". Note that this statement is only true for the harmonics of standing (stationary) waves. [Edit: In the case of progressive waves, the frequency is not affected by the tension - the frequency is that of the oscillator.]

Additional Note.
The simulation in your link is for standing (stationary) waves and is quite sophisticated. It includes transient effects and also the driver is not at a node. These 'advanced' features could confuse someone learning at an introductory level.
 

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'

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...
