Question

A traveling wave in a stretched string is described by the equation;

y = A sin (kx- $\omega$t). The maximum particle velocity is :

• A. A $\omega$
• B. $\frac{\omega }{k}$
• C. $\frac{d\omega }{dk}$
• D. $\frac{x}{\omega }$

Answer 1

The correct option is A

A $\omega$

This is an equation of a traveling 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 ω the angular velocity.
