How to find the wavelength of a sound wave?

AI Thread Summary
To find the wavelength of a sound wave, the formula used is wavelength = velocity / frequency. For a 25 Hz sound wave, the speed of sound is typically taken as 340 m/s, which is necessary to calculate the wavelength. The same approach applies for the 4.5 kHz sound wave, requiring the same speed of sound for the calculation. Users seek clarification on whether to use the speed of sound as the velocity in the equation. Understanding this concept is essential for solving similar problems in acoustics.

Homework Statement


What is the wavelength of a 25 Hz sound wave? What is the wavelength of a 4.5 kHz sound wave?


Homework Equations


wavelength = velocity / frequency or λ = v/f


The Attempt at a Solution


I know that I'm supposed to plug the 25 into the equation, but he didn't give us a velocity, so now I'm stuck. That's what I need help with. :/
The speed of sound is 340 m/s
is that what I'm supposed to use for velocity?

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}...
