B Phase difference in standing wave

Click For Summary
The discussion centers on the phase difference in standing waves, specifically why it is zero when there is an even number of nodes between two vibrating particles. It is clarified that an even number of nodes results in a phase change of π (180 degrees) as one moves past each node. This means that if two particles are separated by an even number of nodes, they will oscillate in phase, leading to a phase difference of zero. The importance of visualizing the wave's snapshot is emphasized to understand this concept better. Overall, the relationship between nodes and phase difference is crucial in understanding standing wave behavior.

Can someone explain why the phase difference is zero when the there is equal number of nodes between the two vibrating particles.

Thank you

You may need to reformulate. Between two particles can be some number of nodes. What would mean for this number to be "equal"?
Equality is a binary operator. Equal to what? Between two particles there is one number of nodes, not two.
 
Sorry, I meant to say even number of nodes
 
The phase changes by Π (180 degree) when you pass one node. You can see this if you imagine (or draw) a snapshot of the wave. On one side of the node all the points go up and on the other side they all go down.

Thread 'Ramjet effect on drone'

I am following someone on Youtube who has built a rocket shaped (4 proprllers) drone for the world speed record ... He was having problems with internal heat from electical control gear and battery inside the sealed rocket (about 1kw waste heat) Speed is 500km/hr , I suggested a 4mm hole in the tip of the nose and 8mm hole at rear which should alow sufficient air cooling .. I said this will increase thrust because the air exiting is hotter .. a bit similar to a ram jet ... was I correct...

Thread 'Why would an atmosphere without greenhouse gasses be colder than with them?'

Quick question that I haven't been able to find the answer to. Greenhouse gasses both warm and cool the atmosphere by slowing heat loss to space. But what would happen without GHGs? I read that the earth would be colder (though still relatively warm), but why? Without GHGs the atmosphere would still be a similar mass and still warmed by conduction from the surface, yet without a means to radiate that heat to space. Why wouldn't the atmosphere accumulate heat over time, becoming warmer? How...
