Progressive Wave Equation

The equation of a plane progressive wave is $Y = 0.025\sin(100t + 0.25x)$ . The frequency of this wave would be

Show answer and solution

Answer: (a)

Compare with $Y = A\sin(\omega t + kx)$ : $\omega = 100\text{ rad/s}$ .
$f = \dfrac{\omega}{2\pi} = \dfrac{100}{2\pi} = \dfrac{50}{\pi}\text{ Hz}$
So the answer is (a) $\dfrac{50}{\pi}\text{ Hz}$ .
