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:
- 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.
