Double slit experiment distance

AI Thread Summary
In a double slit experiment, reducing the slit separation (d) results in a wider fringe pattern on the screen. Specifically, when the slit separation is halved, the distance between adjacent maxima doubles, increasing from 1cm to 2cm. The fringe width (ω) is determined by the formula ω = λD/d, where D is the distance from the slits to the screen and λ is the wavelength of light. Thus, halving the slit separation leads to a direct proportional increase in fringe width. Understanding this relationship is crucial for analyzing interference patterns in wave physics.

In a double slit experiment it is observed that the distance between adjacent maxima on a remote screen is 1cm. Whats happens to the distance between adjacent maxima when the slit separation is cut in half?

As the slit separation decreases, the pattern on the screen spreads out. Look up Young's double slit experiment.
 
SO when the distance is cut in half the screen size will go from 1cm to 2cm or will it go to 4cm ?
 
We have the formula for fringe width as

\omega = \lambda D/d

D= distance between slits and screen
d= width of slits
\omega= fringe width
\lambda= wavelength of light used

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...
