Extreme waves along ocean waters sometimes referred to as freak waves or rogue waves are a focus of much research among scientists. Several merchant reports rogue waves which are estimated to be 25 meters high and 26 meters long. Assuming that these waves travel at speeds of 6.5 m/s, determine the frequency and the period of these waves.
f = 0.26 Hz
t = 3.85 secs
f = 0.25 Hz
t = 4 secs
