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.

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.

Using this stimulation: https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html

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 'Minimum mass of a block'
Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
