calculate the period of the wave

sound travels at 330ms^-1 in air calculate the period of the wave?
Plz help, i don't know how to answer this

Sound waves can have lots of different periods (yet travel at the same speed). For example my voice at 500 Hz will have a period of 2 ms. A dog whistle at 50,000 Hz will have a period of 0.02 ms. The period T is one over the frequency f, i.e. T = 1/f.

Seems to be missing information, is there a frequency given?

Then the question is daft.

lol
If its part of a multi part question check for any information about wavelength in the earlier parts.
Use the relationship
Wave speed = wavelength * frequency
To get the frequency
