Question : 33

Total: 40

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.

0.25 x 10 $^{-3}$ rads $^{-1}$
0.25 x 10 $^{-1}$ rads $^{-1}$
5.00 x 10 $^{2}$ rads $^{-1}$
2.50 x 10 $^{3}$ rads $^{-1}$

Solution:

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 $^{-1}$
