Wave Speed Demo: Rope

This is a demonstration of the dependence of the speed of a transverse wave traveling along a rope on the tension in the rope.

This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

Good demo. I like the backdrop just below the whiteboard...it provides a useful contrast, if the rope is held at a suitable height. I don't know if it was put there intentionally or is always there. Perhaps even better would be a striped background with horizontal stripes by which the amplitude can be measured.

This video gives me a great sense about this topiv

why there is a flick at free end of a whip of string

It would more evident if the movement was repeated continuously...

my teacher has shown me this video thousand times, its a good one :)

The rope looks flexible What material is it made of?

Isn't this because there's less rope with higher tension so the wave travels a smaller distance? So it's not "faster" it's traveling across a smaller distance?

Look this should be a different lesson of it's own look at a responsible man so interested in the young ones future, not even minding his status, thanks alot
