Progressive waves Definition and 11 Threads

So here is my problem I have had a go at this and get an answer of 8.34cm to be my final amplitude The next part that I have been given is to calculate the velocity of when 2 waves are added together. I'm not so sure how to go about this, this is what I have tried anyway Can someone...

The answer is B but I don't understand how. Surely, the string at point P is moving upwards. This video gave a solution but the part that they have indicated as down is a different part of the string and not P.

Homework Statement I don't understand how all the particles in a progressive wave can have the same amplitude. Surely they're all moving along the wave therefore cannot have the same amplitude. Homework EquationsThe Attempt at a Solution

Thinking about establishing a network across campuses in the U.S that would involve on campus groups producing the utensils, straws and cups, etc.. for the campus cafeterias. Was wondering if anyone had any suggestions as to what technology would be best to most efficiently create pretty...

and Homework Statement Ok, so I am doing As physics at the moment and have been left confused by stationary waves. I have read that between adjacent nodes/ even numbers the phase difference is always 0 and between numbers of does it is pi radians. So in the attatched image why is my textbook...

For the wave traveling towards left, the equations is Asin(kx + ωt). How does the same mathematical equation explain the possibility of two initial conditions. In the case of the wave traveling towards right, Asin(kx - ωt) and Asin(ωt - kx) gives two initial conditions Asin(kx) and - Asin(kx) on...

Hi everyone. I'm currently studying waves in physics at the moment but I'm super confused and hoping someone could help me clear up some things. Firstly I'll post what I think it correct (I know it's wrong) and hopefully someone could pick up exactly where I am getting confused. Waves are a...

Homework Statement progressive waves are only for transverse waves ? or it can be also for longitidunal waves? Homework Equations The Attempt at a Solution

i was told that progressive waves has no nodes, why is it so? can anyone here explain please?

1. Homework Statement : progressive waves of frequency 300 hz are superimposed to produce a system of stationary waves in which adjacent nodes are 1.5m apart.calculate speed of progressive waves? 2. The attempt at a solution: should i use 1)v=f*λ=300m/s or 2)v=f*(2λ)=900m/s

Homework Statement I know that progressive waves are waves moving through a medium causing disturbance, transmitting energy. However, I'm confused over some concepts: 1)When the source emits out energy in the form of waves, if it passes through a medium such as water, the energy moves at v...
