The period of this sound wave is 0.02 seconds (1/50th of a second). Show that the frequency of the sound produced is 100Hz.
Is there a mistake with this question? Especially where it says 100Hz.

The frequency (f) and period (P) of a wave a inversely related:
f = 1/P
In this case, the period is 0.02 sec, so the frequency is:
f = 1/(0.02 sec) = 50/sec = 50 Hz.
The book is wrong.
f = 1/P
In this case, the period is 0.02 sec, so the frequency is:
f = 1/(0.02 sec) = 50/sec = 50 Hz.
The book is wrong.
