AI Thread Summary
The discussion revolves around calculating the velocity and wavelength of waves between two nodes on a vibrating string, where the distance between nodes is 10 cm and the frequency is 30 Hz. The initial assumption was that the wavelength is half the distance between nodes, which is confirmed to be correct. The wavelength is thus 20 cm, and using the formula velocity equals frequency times wavelength, the velocity is calculated to be 6 m/s. The participant acknowledges a previous mistake in calculations and expresses gratitude for the clarification. The problem is effectively solved with the correct application of wave principles.

[SOLVED] Wave Behaviour Question

Homework Statement


This is probably going to have a very simple answer, but its a simple answer I don't know. It has to do with figuring out the velocity and wavelength of a wave between 2 nodes. Heres the question.

The distance between two successive nodes in a vibrating string is 10 cm. The frequency of the source is 30 Hz. What is the wavelength of the waves? What is their velocity?


Homework Equations




The Attempt at a Solution


I thought maybe the wavelength would be half of the distance between the nodes but I don't think that's true.

>I thought maybe the wavelength would be half of the distance between the nodes but I don't think that's true.

What makes you think it is not true? Can you draw a diagram to yourself?
 
Well when I used the same theory in another question, the numbers didn't seem right but I will go back and try again.
 
Perhaps in the second case you made an arithmetical mistake.
 
It would appear that was the case :)

I think I've got it, 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}...
