Wave Motion 1 Question 7

7. A travelling wave in a stretched string is described by the equation ; $\quad y=A \sin (k x-\omega t)$

The maximum particle velocity is

(1997, 1M)

(a) $A \omega$

(b) $\omega / k$

(c) $d \omega / d k$

(d) $x / \omega$

Show Answer

Answer:

Correct Answer: 7. (a)

Solution:

  1. This is an equation of a travelling wave in which particles of the medium are in SHM and maximum particle velocity in SHM is $A \omega$, where $A$ is the amplitude and $\omega$ the angular velocity.
