The ropeway wave-runner experiment. Location: Austrian Alps

Описание к видео The ropeway wave-runner experiment. Location: Austrian Alps

Induction, propagation and reflection of a wave along a steel cable. Lenght of cable approx. 550m.
It takes approx. 8 seconds for the wave to travel back and forth, resulting in a wave speed of 495km/h !
This is the average speed. In the upper section of the cable line, the effective speed is slightly higher because of the higher tension. The opposite happens near the lower terminal. So, the higher the wave climbed, the faster it gets: The upper terminal is located 200meters higher than the lower terminal.

(The visual speed may appear slow because the cable was filmed using a 10x zoom).
