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 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
