The horizontal is s or displacement
The vertical is t or time
Answer:
Speed = 0.296m/2
Period = 0.203 s
Explanation:
If by 'long' you mean the wavelength of the waves, then the wavelength 
.
The frequency 
of the waves is 14.8 waves every 3 seconds or
.
Now the relationship between wavelength 
, frequency and speed 
of the waves is:
We put in the values and 
and get:
Now the period 
is just the inverse of the frequency, or
Answer:
