Question

Q7: Explain the difference between the speed ol
travelling along a cord and the speed of a tiny colored part of the
cord.
​

Answer 1

Answer:

A transverse wave travelling along a cord shows a pattern (the wave form) shifting in one direction, with a certain speed. This is the wave speed.

The tiny coloured part of the cord shows a simple vibration, with a certain amplitude. The speed of this part varies with time. In case of a sine wave, the vibration is harmonic; the maximum speed depends on the amplitude of the vibration.
