Period: The period is the time it takes for one wave to pass a given point. We can find the period by dividing the time it takes for 20 wave crests to pass the fisherman (one minute) by the number of wave crests (20). Period = 1 minute / 20 crests = 0.05 minutes/crest = 3 seconds/crest Frequency: The frequency is the number of waves that pass a given point in one second. We can find the frequency by taking the reciprocal of the period. Frequency = 1 / Period = 1 / 3 sec/crest = 0.33 crests/sec Speed: The speed of the waves can be found by multiplying the distance between wave crests (2.0 meters) by the frequency. Speed = Distance / Time = 2.0 m/crest x 0.33 crests/sec = 0.66 m/sec Therefore, the Period of the waves is 3 seconds/crest, the Frequency is 0.33 crests/sec and the Speed of the waves is 0.66 m/sec.
