Question on: JAMB Physics - 2021
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 Option: C
y = A sin (wt + 0)
y = 0.25 x 10\(^{-3}\)sin (500t - 0.025x)
w = 5.00 x 10\(^{2}\)rads\(^{-1}\)
