**Hint 2**

For a sinusoidal voltage or current of frequency:

$$$f=\frac{1}{T}$$$

where
$$T$$
is the period.

Frequency is the number of repeating event occurrences per unit of time. The SI units for frequency is hertz (Hz). For a sinusoidal voltage or current of frequency:

$$$f=\frac{1}{T}$$$

where
$$T$$
is the period in seconds.

$$$1\:Hz=\frac{1}{sec}=sec^{-1}$$$

$$$sec^{-1}$$$
