4.15 What is the phase relationship in stationary waves

[@TheRealDeal0781]

thank you so much 💗💗 no other explanation has been this helpful

Glad it helped!

Clearest explanation I could find, thank you!

Thanks I love you

Welcome 😊

So whether the particles are separated by 2 nodes or 4 nodes, the phase difference would be 0 degrees? Not like 360, 720,1440,.. and so on(still in phase but at different angles) ? Is that only for progressive waves? btw GREATTT explanation!! thank youu :)

[@MrNagaPhysics]

In this case saying they are in phase, 360, 720 ... are all equivilant statements. They mean the same thing. So yes you can just say they are in phase. In progressive waves sometimes it's useful to say 360 , 720 and so on to see how many whole wavelengths seperate the two points. In stationary waves this is pointless because the whole loop is in phase. Does that help? Glad you found the video useful.

You're welcome.

Why do the phase difference of any two points on standing wave are either 0 or 180?

[@MrNagaPhysics]

Firstly phase is to do with what stage of a cycle one point is compared to another. If they're both at maximum they're in phase ( the maximum can be different for each point for example AN has a largest maximum). If they're both at minimum or equilbirum at the same time they're in phase. If one is at maximum and the other is at minimum they're in antiphase. If both are at equilbirum but one is going up and the other is going down they're in antiphase. Try this video to understand what phase means better: kzbin.info/www/bejne/aJylfqqmjdqbsLc&pp=gAQBiAQB

very very clear ❤❤thanks sir.

[@MrNagaPhysics]

Most welcome.

[@Hogrider885]

whats the phase difference between an antinode and an adjacent node?

[@MrNagaPhysics]

It wouldn't make sense to talk about phase difference between a node and antinode because the node isn't even oscillating. Do you mean between antinode and its adjacent antinode? ( 180 degrees)

[@Hogrider885]

@@MrNagaPhysics this was the question asked in our test and ik it doesn't make sense but the answer everyones giving is pi/2. The options were pi/4,pi/2 ,pi and 3pi/4. I dont understand how pi isn't the one which makes the most sense.

[@MrNagaPhysics]

That's because the wave you'r talking about is a progressive wave. This video is for a stationary wave. you need to watch this video. kzbin.info/www/bejne/aJylfqqmjdqbsLc

[@Hogrider885]

@@MrNagaPhysics the question says stationary wave, thats why i was confused.

[@MrNagaPhysics]

hmmm, strange. Maybe you can post a picture of the question on the sub reddit.

Nice
