D)f/T
E)T/f

Question

Quizplus · Accepted Answer

The angular frequency of a sinusoidal wave is given by $2\pi f$, where $f$ is the frequency of the wave. Since the frequency $f$ is the reciprocal of the period $T$ (i.e., $f = 1/T$), the angular frequency can also be expressed as $2\pi/T$, which matches the form given in option B.

Let F Be the Frequency, V the Speed, and T π\piπ
