Finding the distance between slits in double slit experiment

AI Thread Summary
The discussion centers on calculating the distance between slits in the double slit experiment. The user initially struggled with the problem and shared a link to the question, along with their sketch and calculations. They derived a value of 2.92 x 10^-4 m for the slit distance. Concerns were raised about needing to use a diagram for a 12-mark question, indicating a desire for a thorough approach rather than a straightforward application of a formula. Ultimately, the calculations were confirmed by another participant, validating the user's result.

Hi so I have been struggling on a part of a question that I'm not too sure on how to solve
For some reason PF is not allowing me to pose an image of the question on here so I have provided a link to it

Question link:

And here is what I tried to do so far, I drew a sketch of a diagram to help me derive the formula that I need

Sketch:
Working out:

I got little d to be 2.92 x 10-4m

Any help would be really appreciated! Thanks

I computed it also, and got the same answer.

Sure. What is your problem ?

Sorry I just got threw off here as it was set to be 12 marks, so I though I had to make use of a diagram or something to get to an equation I can use to find d. And not just dive straight into a known general formula to calculate d, as it would seem to be too much little work.

Looks about right now then I guess

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}...
