Standing question - real straightforward- Workings given

AI Thread Summary
The discussion revolves around calculating the harmonic of a wave given specific parameters: W=27.2, K=15.71, and A=0.1. The initial calculation suggests a harmonic of 4.5, which is problematic since harmonics must be integers. The user notes the presence of a node at one end and an antinode at the other, indicating a specific wave configuration. They also calculate the wavelength as 0.4 using K=2π/λ. Clarification is sought on whether their assumptions about the wave's characteristics are correct.

W= 27.2

K=15.71

A=0.1

Now to determine the harmonic.

This formula gives the harmonic to be 4.5. This can't be possible since n has to be an integer.

I realize this wave has a node at one end and an anti node at the other.

I also realize that this wave on the string has a wavelength =0.4 by using K=2pi/lambdaWhat do I do ? :(

Or am I wrong in assuming this is a wave has a node at one end and an anti node at the other ?
 

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}...
