Standing wave interference pattern problem

AI Thread Summary
In a standing wave interference pattern, a wavelength is defined as the distance between consecutive crests or troughs. For complete destructive interference to occur, the wavelengths and amplitudes of the two waves must be identical. Additionally, the troughs of one wave must align with the crests of the other, meaning they are exactly out of phase. This condition requires that the waves share the same frequency content and power spectrum. Understanding these principles is crucial for analyzing wave interactions in various physical contexts.

In a standing wave interference pattern, what distance constitutes a wavelength?

For complete destructive interference, what must be true of the wavelengths and amplitudes of the 2 waves?

Wavelength - Disatance from crest to an adjacent crest or trough to an adjacent trough. (They will be the same length)
For complete destructive interference the wavelengths and amplitudes must be the same and the troughs of one wave must line up with the the crests of the other (and vice versa).
 
For complete destructive interference the waves must have exactly the same frequency content and power spectrum (amplitudes of all the different frequency components) and the waves must be exactly out of phase.
 
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 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
