for 30 min my physics professor was trying to explain this. :<

@Kiriha15 Did the video clip help you?

[im2013026]

i have a question that I desperately need need an answer to. When you make a transverse wave in a slikny, does the reflected wave have a lower speed than the incident wave?

[mrg3]

@im2013026 What should the wave sped depend upon? In the usual model, the speed depends upon the tension and the mass per unit length of the slinky. Is there anything in those ingredients that could depend upon whether the wave was reflected or not?

could have been better if a wave train was animated, just a single pulse doesnt give a clear idea of further things

[mrg3]

@misbahuddinathar ,There is a companion video with harmonic waves.

simple and almost best describing!

[Pinkpolkadotcats]

whoa! thanks so much. exactly what I needed to better understand my physics homework. :-)

I like that part when the wave moves

[schnouttz]

In 6 seconds, you just did what a half hour physics explination could not.

[fctapes]

YES

!

@mrg3 of course :D

Wait, is my Youtube just f*cked up, or is there no 0:06 :D

@im2013026 The transverse, reflected, indirect wave is exponentially slower than the the longitudinal wave. Imagine a broomstick 5 yards long and situated against my head. For a transverse wave, you shake it - I will see the energy before it gets to me. In slow motion the pole would look like a snake - a sinusoidal wave.

For a longitudinal wave, you pound the end of that broomstick with a hammer. No delay, instant pressure/power. Longitudinal waves exceed light speed.
