The equation of a wave traveling along the positive x-direction is given by; y = 0.25 x 10\(^{-3}\) sin (500t - 0.025x). Determine the angular velocity of the wave motion. 

A.

0.25 x 10\(^{-3}\)rads\(^{-1}\)

B.

0.25 x 10\(^{-1}\)rads\(^{-1}\)

C.

5.00 x 10\(^{2}\)rads\(^{-1}\)

D.

2.50 x 10\(^{3}\)rads\(^{-1}\)

Correct answer is C

Using y = A sin (wt + 0)

Given y = 0.25 x 10\(^{-3}\)sin (500t - 0.025x)

By comparing, w = 5.00 x 10\(^{2}\)rads\(^{-1}\)
