you are in a row boat on a lake and a speed boat passes you. your boat starts to bob up and down. you observe that you bob every .5 seconds, and the waves are 3.0m apart what is the wave speed?

T = .5 seconds is the period and λ = 3.0 m is the wavelength. Frequency is f = 1/T = 1/0.5 = 2 Hz or 2 s^-1. Wave speed v is the product of frequency and wavelength, so v = λf = (3 m)(2 s^-1) = 6 m/s.

Frequency f = 1/T where T is the periodic time
You are given T = 0.5
Therefore f = 2 Hz
velocity = frequency * wavelength
= 2 *3 = 6 m/s
