A wave is described by y(x,t)= 0.1 sin(3x - 10t), where x is in meters, y is in centimeters and t is in seconds.The angular frequency is:
A)0.10 rad/s
B)3.0 rad/s
C)10$\pi$ rad/s
D)20$\pi$ rad/s
E)10 rad/s

Question

Quizplus · Accepted Answer

The angular frequency ($\omega$) is given by the coefficient of $t$ in the argument of the sine function, which is 10 rad/s in this case.

A Wave Is Described by Y(x,t)= 0 π\piπ Rad/s D)20 π\piπ Rad/s E)10 Rad/s

A Wave Is Described by Y(x,t)= 0 $\pi$ Rad/s
D)20 $\pi$ Rad/s
E)10 Rad/s
