What is the effect of decreasing the widths of slits in double slit experiment?

AI Thread Summary
Decreasing the widths of slits in the double slit experiment increases diffraction, causing energy to spread more across the screen rather than concentrating near the center. The number and placement of interference fringes remain unchanged, but their relative brightness is affected. Enhanced diffraction is necessary for light to reach off-center fringes. This phenomenon illustrates the relationship between slit width and diffraction patterns in optical experiments. Understanding these effects is crucial for analyzing wave behavior in light.

You get more diffraction so the energy spreads more on the screen instead of being concentrated near the center.
 
Will the number of fringes decrease or increase?
 
The number or placement of the fringes doesn't change. Their relative brightness changes. Diffraction is required for light to reach the off center fringes.
 

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}...
