Number of Nodal Lines in Two-Point Interference Pattern

AI Thread Summary
In a two-point interference pattern, increasing the wavelength of the sources leads to an increase in the number of nodal lines. This occurs because a longer wavelength results in a lower frequency, which allows for more opportunities for destructive interference. As the wavelength increases, the spacing between nodal lines also increases, creating more distinct nodal lines in the pattern. The relationship between wavelength and nodal lines is crucial for understanding interference phenomena. Thus, longer wavelengths contribute to a greater number of nodal lines in the interference pattern.

The Attempt at a Solution



I said they would stay the same but its wrong.

as the wavelength increases there will be more more nodal lines as the frequency will also increase. with faster wavelenghts the frequency will increase which means the waves will be shorter which will allow for more destructive interference which are nodal lines.
 
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...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
