The formula for the period of a sine/cosine function is . You can figure this out without looking at a graph by dividing  with the frequency, which in this case, is 2. Recall that sine passes through , while cosine passes through .

The only remaining obstacle, is whether the function is sine or cosine. The distance between the maximum and the minimum is half the wavelength. Our tips from experts and exam survivors will help you through.

Begin by realizing we are dealing with a periodic function, so sine and cosine are your best bet. The equation for this function is in the form. The unit for time period is 'seconds'. In this case, one full wave is 180 degrees or  radians.

I was thinking of finding all the values of time (X axis) when the height of the wave (Y axis) goes to 0 and then work from there. Reveal answer \[T = 1 \div 400\] \[T = 0.0025~s\] Calculating wave speed.
