The frequency of the sinusoidal wave

y = 0.40\,\,\,\cos \left[ {2000t + 0.80x} \right]

would be

View answer and explanation

Correct option: D

\frac{{1000}}{\pi }Hz

Option D (

\frac{{1000}}{\pi }Hz

) is correct because the frequency is calculated from the coefficient of time in the given sinusoidal wave equation.
