Double Slits experiment central fringe intensity

AI Thread Summary
In a double slits experiment, widening each slit by two times is believed to double the intensity at the central fringe, resulting in an intensity of 2I. The reasoning behind this is that increasing the slit width allows more light to pass through, thereby increasing the intensity. The relationship between slit width and central fringe intensity suggests that greater slit width correlates with higher light intensity. This concept is fundamental in understanding the behavior of light in interference patterns. Overall, the discussion emphasizes the direct impact of slit width on intensity in the double slits experiment.

Homework Statement


In a double slits experiment, the intensity at the central fringe is I. What will be the intensity at the central fringe when each slit is widened 2 times?

But what is the reasoning?
What is the relationship between the central fringe intensity and the slit width?
 
I think that when the width of the each slit is doubled then the amount of light passing through will be double as well as the intensity
 

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'

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...
