Double slit interference experiment

AI Thread Summary
Introducing a separate baffle around two different substances can significantly impact the interference fringes in a double-slit experiment. Adding a transparent material with a different refractive index in the slits may cause a shift in the fringe locations. If interference is blocked, the result will be two single-slit patterns instead of the expected double-slit interference. The discussion also highlights the importance of using a coherent light source and a flat projection surface for accurate results. Overall, the setup and materials used play a crucial role in the behavior of interference patterns.

If separate baffle around two different substances，What impact on the interference fringes？

What do you mean with "If separate baffle around two different substances"?

What impact on the interference fringes？
If you plan to add some transparent material (with different refractive index) in the slits: The fringes can shift in their location.
If you block any possibility for interference: The double-slit interference does not happen any more, you get two single-slit patterns.

Change the damper's own material
 
Which damper, which material?

Actually, I have no idea what you are asking. Can you add some context, sketch or other explanations?

You mean the screen's material.Well it doesn't matter where you project that beam,it should be a nice flat surface,thats all you need,and a coherent light source.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
