How Does Air Behave as Sound from a Tuning Fork Travels to a Listener?

AI Thread Summary
As sound travels from a tuning fork to a listener, the air experiences compressions and rarefactions, corresponding to maximum and minimum pressure, respectively. The sound wave propagates through the air at a speed of 340 m/s, creating these alternating pressure changes. The graph illustrating air pressure variation over time at the listener's position would indeed resemble a sine curve, reflecting the periodic nature of sound waves. Understanding these concepts is crucial for grasping the fundamentals of sound propagation. The discussion confirms the accuracy of these explanations.

Hi there

Can someone please check if I have answered these correctly?

A tuning fork generates a pure tone at 523Hz (v=340m/s)

...Explain what happens to the air as the sound of the tuning fork travels towards the listener?...is it right to say that compressions and rarefractions take place which corresspond to max pressure and min press. respectively.

Also it asks to sketch a graph how the air pressure varies with time at the position of the listener...is this just a sine curve?

Thanks

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}...
