AI Thread Summary
To find the speed of a wave in a new medium with different density, the relevant equation is c = √(T/μ), where c is the wave speed, T is the tension, and μ is the density of the medium. The wave speed in the first rope is given as v_1, and the density is μ_1. When the wave transitions to the second rope with density μ_2, the new wave speed v_2 can be calculated using the same tension T, assuming it remains constant. The relationship indicates that as density increases, wave speed decreases, provided tension is unchanged. Understanding this principle allows for the calculation of v_2 in the new medium.

There is a tranverse wave induced in a rope with density \mu_1 with velocity v_1. It reaches a rope of different density \mu_2. What is the speed of the wave in the new medium, v_2. This is pretty simple but I just don't know what equation to start with.
 
Physics news on Phys.org
c = \sqrt{T/\mu} c is wave speed and T is tension on the string
 
Thank you very much, I feel pretty stupid now :)
 
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}...
