Limitations of Young's double slit experiment

AI Thread Summary
The discussion focuses on improving the Young's double slit experiment by suggesting variations in experimental parameters. Key improvements include adjusting the slit distance, slit size, and wavelength of the light used. The importance of changing one independent variable at a time to accurately observe phenomena is emphasized. Additionally, the potential for new scientific discoveries through these small variations is highlighted. Overall, refining the experimental setup can lead to more insightful results.

Homework Statement


From a procedure standpoint, our experiment consisted of a laser pointer on a retort stand with a holder, shining through a piece of sheet with slit measurements (I believe it's acetate) and measuring the height of the maxima on a whiteboard. What could be improved with this experiment?

What things are changeable so that you can get a variety of measurements?
 
I understand that there are other IV's that could have been tested, such as light intensity, wavelength etc... but what is wrong with specifically the experiment I did? The independent variable was the slit distance between the two slits
 
As a scientist you need to vary parameters one at a time to truly test a phenomena. In your case, distances to the slit or slit size or wavelength are parameters that you can vary.

New science is often discovered by doing these small variations and then observing something interesting in the results.

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}...

Thread 'Struggle to understand the concept of the 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...
