Speed of WaveMediumQuestion 31346

Question

If a string is struck transversely and a pulse is created, the pulse speed depends on:
  1. A
    How hard it was struck
  2. B
    Tension and linear density only
    Correct
  3. C
    Strike angle
  4. D
    Both tension and how hard it was struck

Correct answer

Tension and linear density only

Explanation

Wave speed v = √(T/μ) is a property of the medium, not of the disturbance. A hard strike creates a larger amplitude, not a faster pulse.
