Question 1 Report

The equation of a wave travelling along the positive x-direction is given by;

Y = 0.25 x 10-3 sin (500t - 0.025x).

Determine the angular frequency of the wave motion.

0.25 x 10-3rad s-1

0.25 x 10-1rad s-1

5.00 x 102rad s-1

2.50 x 103rad s-1

Answer Details

The equation of the wave is given as Y = 0.25 x 10^-3 sin (500t - 0.025x). To determine the angular frequency of the wave motion, we need to find the coefficient of 't' in the argument of the sine function, which is 500. The angular frequency is then given by 2π times the frequency, where the frequency is 500/2π. Therefore, the angular frequency of the wave is 5.00 x 10² rad s^-1. So, the correct option is: - 5.00 x 10² rad s^-1
