AI Thread Summary
To optimize organ pipe modes with vent holes, the placement of holes should be aligned with the positions of antinodes for the desired modes. For the third mode, a vent hole should be located approximately one-third of the way down the pipe, while for the fourth mode, it should be about one-quarter of the way down. This positioning enhances the resonance of the respective modes. The discussion references visual aids to clarify the relationship between nodes and antinodes in open and closed organ pipes. Proper vent hole placement is crucial for achieving the desired sound characteristics in organ pipes.

Homework Statement


Where would you locate a small vent hole to encourage the third mode of an open pipe? The fourth mode?

Homework Equations



Hint: Where is a node of the desired mode?

The Attempt at a Solution



Does this mean 1/3 of the way down for mode 3 and 1/4 of the way down for mode 4?

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}...
