a girl lying on a an air mattress in a wave pool that is 3 m deep, with waves 0.5 m in height that occur at 7 s

i was just wondering if i would start off at -0.5 m, and then at 3.5 s, i would plot at point at 0.5 m, and then at 7 s, i would plot at point at -0.5 again? in that case would 7 be considered the period of the function?

**Damon**, Saturday, January 1, 2011 at 4:30pmThey mean 7 s is the period I believe.

Remember the depth of the pool, 3 meters.

I assume by wave height they mean the amplitude and not the height from bottom to peak which would be 1 here

First point is at 3-.5 = 2.5 m

t---- h

0000 2.5

1.75 3

3.50 3.5

5.25 3

7.00 2.5

8.75 3

10.5 3.5 etc

but, i would assume the height of the wave would be -0.5 to 0.5 because wouldn't be calculate it in terms of the water's surface?
